An RF driver generates a fixed or variable frequency signal supplied to the acousto-optic devices transducer. This in turn uses the piezoelectric effect to very precisely convert the RF signal to an acoustic wave.

An RF driver generates a fixed or variable frequency signal supplied to the acousto-optic device’s transducer. This in turn uses the piezoelectric effect to very precisely convert the RF signal to an acoustic wave that propagates within the acousto-optic device’s crystal. The frequency and intensity of the applied signal will determine how much an optical beam is modulated, deflected, or tuned.

An acousto-optic device and its RF driver should be selected as a unit to optimize speed and stability for each application. Additional driver features include first pulse suppression, synchronization, pulse shaping, and multichannel operation. We offer a wide variety of stable high frequency drivers with analog and digital modulation capability. Voltage controlled oscillators (VCOs) vary the oscillation frequency via the input voltage, and are a costeffective solution for applications with less stringent frequency stability and linearity requirements.

Direct digital synthesizer (DDS) drivers offer higher stability, with fast switching time and high resolution. They can create random waveforms from a single, fixed-frequency reference clock, and thus are ideal for pulse shaping and special functions. They also allow frequency to be varied on the order of a few hundred nanoseconds, and are inherently very linear. DDS drivers are software driven, and can be run from a user-friendly interface (a GUI), or controlled directly via computer driver commands. Our high-performance multi-frequency DDS drivers generate up to 8 channels of RF frequencies simultaneously.

As our AO product lines expand, we are creating more flexible, adaptive RF drivers with dual analog/digital operation and configurable firmware to accommodate functionality like triggering and temperature control without the need for new hardware. Our OEM designs, in contrast, are optimized to each customer’s application, maximizing performance in the required form factor.

CHOOSING AN RF DRIVER
The needs of the AO device will dictate the choice of RF driver. The primary factors to consider are shown below, though speed, duty cycle, and special functions are also important.

  • RF power: ranges from 150 W
  • Modulation: digital or analog
  • Frequency of operation: may be fixed, variable (linearly swept), or programmable
  • Stability: influencing choice of VCO vs DDS when frequency is not fixed
  • Number of channels: number of output ports or number of output tones from a single port
  • Special functions: pulse-killing, synchronization, etc.

MODULATION: DIGITAL VS ANALOG

The modulation mode determines how the applied RF power is varied, and thus the intensity of diffracted light. In digital modulation, the RF power is applied in an on/off state via an applied TTL signal, thus controlling whether the beam is diffracted. In analog modulation, the RF power is controlled through application of a voltage within a specified range, yielding control over the diffraction efficiency and allowing shaping of that waveform in time.

FIXED VS VARIABLE FREQUENCY DRIVERS

Fixed frequency drivers provide a single output frequency which is matched to the AO device. Offered from 24-440 MHz, fixed frequency drivers may be controlled via analog or TTL input, some with manually adjustable output RF power. These are used most often for modulation applications.

Variable and programmable frequency RF drivers allow active control of output frequency. Voltage controlled oscillators (VCOs) provide a linearly swept (variable) RF drive frequency, and are flexible enough to be used for any AO device. Direct digital synthesizer (DDS) drivers offer programmable frequency. They can create random waveforms from a single, fixed-frequency reference clock, and thus are ideal for pulse shaping and special functions. DDS drivers are software driven, and can be run from a user-friendly interface (a GUI), or controlled directly via computer driver commands. Our high-performance multi-frequency DDS drivers generate up to 8 channels of RF frequencies simultaneously.

DUAL DRIVERS

Dual drivers allow simple or complex digital waveforms to be synthesized, converted to analog signals, and amplified to drive the AO device. This gives great flexibility; for example, it allows the driver to provide multiple programmable frequencies or to swap freely between multiple, complex, bespoke waveforms.

FREQUENCY AGILITY AND CONTROL

We offer Direct Digital Synthesizer (DDS) drivers that offer high stability and linearity, with fast switching time and high resolution. They are capable of creating arbitrary waveforms from a single, fixed-frequency reference clock, and thus are ideal for pulse shaping and special functions. DDS drivers can be run from a GUI or via driver commands in two modes: 1) random access, with digital words mapping to specific frequencies, and 2) chirped mode for continuous scanning in frequency increments. DDS drivers are also referred to as DFS (digital frequency synthesizer) drivers.

Our technical support team is available to advise on selection and optimization of RF drivers for specific applications, as well as customization of products for OEM integration.

3. Fiber-Q RF Driver

Each Fiber-Q acousto-optic modulator requires an RF driver to control the embedded acousto-optic crystal, as modulation of the beam depends upon the frequency and intensity of the applied RF signal.

The RF signal which generates the acousto-optic wave in the acousto-optic crystal can do so very precisely at a fixed or variable frequency, and is created using a transducer mated to the acousto-optic crystal and driven by the piezoelectric effect.

Analog, digital, and combined RF drivers are available for use with the Fiber-Q series. All are designed for dependable stability and high frequency operation, with compatible options for the full line of visible and NIR Fiber-Q products. The speed and stability of a modulator is limited by the stability and speed of the RF driver, and thus the two should be selected as a paired unit to optimize performance, features, and application-specific options.

The primary factors to consider when selecting an RF driver include the operating frequency, the required rise/fall time of the application, and whether analog or digital modulation is needed. RF power, duty cycle, stability, and variable vs fixed frequency are also relevant.

Drivers for the Fiber-Q series of modulators are designed for constant RF power output, fast modulation, and with conductive cooling via the baseplate. When tuned together with the modulator, they offer stable, dependable modulation to enable all-fiber laser systems.

CONTROL WORD CALCULATIONS

The output frequency and step size is a function of the clock rate and the FREQUENCY SELECT (FS) data. The output frequency can be calculated from the formula:

FS[29:0] = Fout (231) / 1000 MHz

Where Fout is output frequency in MHz

The LATCH function (pin 16) is a TTL compatible input which is used to load new frequency information into the driver. Frequency data is loaded into the driver when the signal on the LATCH pin goes from HIGH to LOW (falling edge).

The DELTA FREQUENCY LATCH function (pin 36) is a TTL compatible input which is used to load new data frequency information into the driver. For Delta frequency word, the same calculation is used as the output frequency with negative values being entered in twos complement data is loaded on the falling edge.

Master RESET is a TTL active HIGH and resets the accumulator to zero, ie, no frequency output, when a TTL HIGH is applied to pin 17. This is pulled LOW via. a 1 K resistor.

5. 6000 SERIES DRIVER (20-450MHz, 2 channels, 15W)

15 W Output – Configurable Operation

Our 15 W output RF driver provides up to two independent RF channels with a fast parallel interface as well as USB controllability.

Ideally suited for controlling a two element phased array acousto-optic (AO) beam deflector (MUX mode), the driver can also be used to drive two single element AO beam deflectors for two dimensional scanning (Dual Channel mode). The 6000 driver has additional flexibility for controlling AO tunable filters (multi-tone mode). With its arbitrary waveform playback capability, multiple wavelengths can be simultaneously diffracted by tunable filters and multiple beam spots can be generated by beam deflectors.

Two independent 15 W RF amplifiers are housed in a compact form factor with a fast parallel frequency programming interface. Remote control over an included USB interface is also available with an intuitive command set and GUI. Dual amplitude and relative phase control inputs are included on the rear panel with the parallel interface connectors. Capabilities include dynamic frequency chirp control. An all digital option allows high speed programming of frequency, amplitude and phase. The default, power-on is stand-alone mode, not requiring PC control; connecting the USB connection enables a Host PC mode. A single channel version is also available.

The 6000 driver is available in three frequency bands, and each unit includes a monitor output that covers the entire 20-450 MHz frequency band. Driver functionality can be re-configured over the USB interface.

7. AOM Driver (RF Driver) 3910 Series (45-500MHz, 8W)

Next Generation AO Modulator Driver

The 3910 series RF drivers offer a significant upgrade over our 2910 series while maintaining backwards compatibility.

The 2910 series RF driver has been a workhorse for powering AO modulator applications over the last decade. The line has received a complete makeover to further enhance the success of this signature driver. All of its functions have been improved and a few key features have been added while maintaining its affordable price.

The 3910 modulation input now allows the user to switch from three modulation schemes: Digital, Analog and Digital+Analog. This function will be standard on all models. The RF power has been doubled from 4Watts to 8Watts (at +28Vcc). The 3910 features more efficient power consumption than its predecessor. The Frequency range has been increased up to 500MHz, making it able to control any of the currently available AO modulator models. The rise time is <4ns at all power levels and frequencies >250MHz. Another new feature is the optional ability to synchronize the driver to an external clock reference. The 3910 RF driver offers more power, higher frequencies, faster rise times, more modulation choices, synchronization capabilities and the latest electronic components over the 2910 series driver while maintaining the same footprint and pricing.

8. A35xxx (40 to 350MHz, 5W)

The A35xxx RF driver series provides up to 5 Watt output power. Various types cover a frequency range from 40 to 350 MHz.

The maximum RF output power is adjustable by an internal potentiometer. The analogue modulation voltage controls the output power from 0 to 100% of the adjusted maximum power. Additionally to the analogue modulation voltage a digital modulation control signal can switch on and off the RF power. An operation scheme below (page 5) illustrates the interaction of the two modulation signals in detail. Both the analogue and digital modulation are characterized by extraordinary on/off ratios of at least 65dB. The driver can be operated with modulation frequencies (analogue and digital) up to 25% of the carrier frequency and 50 MHz maximum. Optimum EMC shielding and mechanical protection is achieved by an aluminium casing. The base plate serves for mounting as well as for heat dissipation.

STCT Series AOM Drivers (RF Drivers, AOQ Drivers)

RF drivers can generate RF signals at fixed or variable-frequencies. Specified waveforms could be produced by different modulated signals to meet the requirements of different acousto-optic components and determine how much an optical beam is modulated, deflected, or tuned. Our RF drivers are able to generate RF signal at 27.12MHz, 40.68MHz, 68MHz, 80MHz, 100MHz, 120MHz, 200MHz, 250MHz, 300MHz and even higher, with RF power up to 120W. A variety of operating modes are available including FPS, PPK, R05 and A05 (Analog). Acousto-optic variable-frequency series drive of frequency shifter, deflector and filter, can output RF signal with high precision and broad frequency range, and support digital control, analog control, etc. PC software is equipped with which users can set the frequency and power at will. The frequency sweeping and other functions can also be set (TA series). For high-speed frequency conversion applications, it is capable of fast frequency switching (TB series). These drivers are matched with our AOMs and other acousto-optic components.
