PS5023 flashlamp driver is designed for pumping solid-state lasers with variable or long pulsewidth lamp discharge. It features variable pumping pulse in 0.5 – 10 ms range and output voltage of up to 550 V. Custom versions can achieve tens of milliseconds pulse duration.

Excellent pulse-to-pulse voltage stability. The charger is based on resonant inverter topology which is most efficient way to charge capacitive loads. Innovative design of charger circuit allows to charge capacitor bank with an excellent precision of 0.2%.

Built-in serial ignition circuit. The driver features a built-in serial ignition circuit. It greatly simplifies the design of laser head since external triggering circuit is not required anymore. The simmer module provides up to 900 V striking voltage. The flashlamp is ignited by 16 kV pulse of approximately 1 μs duration, applied to the flashlamp cathode. The ignition circuit reliably ignites flashlamps with up to 200 mm arc length.

Remote control. Microprocessor-based control allows seamless integration of the driver into sophisticated laser systems. The charge voltage, repetition rate and pulse duration can be controlled remotely through LAN, CAN or RS-232 interface. In addition, the interface allows monitoring of status and error messages as well as measure output energy and current to the lamp. The discharge pulse can be triggered from external pulse generator facilitating synchronisation of several units.

Built-in simmer power supply. The simmer power supply improves pulse-to-pulse stability and flashlamp lifetime. It is a constant current source producing 600 mA current at up to 300 V output voltage. Other current values are available optionally. Linear xenon flashlamps of 4–6 mm bore diameter and arc length up to 200 mm are reliably simmered.

Modular design. The output parameters of power supply can be easily modified to meet customer needs subject to active lasing material, average output power or pulse energy. The average output power of the driver can be scaled up by paralleling several charger modules. Up to four modules with resulting 4.8 kJ/s peak charging rate can be fitted into a single 19” body.

Seamless integration. The driver can be easily integrated with EKSPLA cooling units of PS1223 or PS1245 series. Up to 6 units can be mounted into up to 25U height 19” racks providing powerful yet compact laser pumping cabinets.
