PRODUCT DESCRIPTION
1. LDD Series Laser Diode Drivers
The laser diode driver LDD-AAVV is a high current-constant laser diode driverwithoutTEC control. Current control,transient suppression, short circuit protection, and over current limit areprovided. A digital meter shows the output current and output voltage.
Features:
* Compact in size and light in weight.
* Modular design for convenient maintenance.
* Excellent performance.
* Portable for easy moving.
Specifications:
Model: LDD-AAVV-xx
LDD-laser diode driver
AA-maximum output current(A). The output current is continuously adjustable.
VV-maximum output voltage(V). The output voltage is determined by current & diode’s resistance.

Remark:
To select a driver, you may finalise the outputvoltage first and then finalise maximum output power. The maximum outputcurrent will be the maximum power divided by the output voltage.
2. LDD Series 3in1 Lser Diode Drivers
In a diode pumped Nd:YAG laser marker, adiode driver, a Q-switch driver and a DC power supply are needed. They areindividual with large size and then the size of the laser marker is also large.It is not convenient to move the laser marker due to large size. We havedeveloped a “3 in 1” laser power supply and the above power supplies areintegrated into one unit with compact size.
Features:
* Compact in size and light in weight.
* Modular design for convenient maintenance.
* Excellent performance.
* Portable for easy moving.

If “3 in 1” laser power isused in a laser marker, the marker will be simple and it consists a laser headwith a marking head and a power supply as shown as follows. The marker will beportable.
“2 in 1” laser power isalso available. It includes a diode driver and a Q-switch driver (RF driver).
3. LDD3 Series Diode Drivers
Diode driver isdesigned to supplying the laser diodes and diode arrays by pulsed current up to200A or DC current up to 64A. Produced as an OEM module. The driver provides awide range of smooth change of parameters of radiation.
Series SSF60XXis widely used in laser technology complexes (marking, welding, soldering,cutting), medical devices, measuring laser equip-ment (spectrometers, lidar,range finders).
