Pulse Laser Power Supply

Pulsed Flashlamp Power Supply + EO Q-switch Driver (STLDF Series)

STLDF series flashlamp-pumped laser power supplies are designed to drive solid state-state lasers and EO Q-switches. Power supplies are complete pumping solutions and include all required modules - bank of storage capacitors, charging module and discharging circuit with triggering and simmer modules.

Power supplies are performed accordingly to 19-inch specification. Height is 4U. Embedded touchscreen controlled computer allows changing of all principal parameters such as output voltage, flashlamp pulse duration and pulse repetition rate.

By default the laser power supply is supplied in serial triggering and partial discharge modification. Modifications for external triggering or complete discharge are available on request. Also the laser power supply can be equipped with Pockels cell driver (Q-switch driver). In this case user obtains a possibility to control output voltage level and delay between flashlamp pulse start and Q-switch pulse (pulses). This ability is significant for adjusting user system for best performance.

Options

Three standard output power levels are available:

- 1.75kW, PFC > 0.85

- 3.5kW, PFC > 0.85

- 2 kW, PFC > 0.98

A variety of output voltages, longer pulse duration, complete discharge, parallel or serial triggering, embedded or external Pockels cell driver are available on request.

Pulsed Laser Power Supply (STLDP Series)


Box I	Box II	Box I	Box II

STLDP series pulse laser power supplies are designed to drive xenon lamps in pulse Nd:YAG lasers. It is a constant-current switching power supply. A power supply consists of two boxes.

A pulse shape can be programmed and be divided into maximum 15 segments as shown in the figure. Each segment consists of a width (tn) and a current (An). The width and current can be individually and independently set. The capacitor bank is 16400uF, maximum output electrical pulse energy is 1200J and maximum output voltage is about 540V.

A power supply consists of two boxes or three boxes: one control box and one capacitor box or two capacitor boxes.
