SDC-150A is a complete solution for powering and controlling a diode-pumped solid-state Nd:YAG laser. Our module includes a pulsed current source to drive pumping diodes, TEC controller for their thermal stabilization and embedded Pockels cell driver for generation of Q-switched pulses.
The module requires a 28 V DC (±7 V) power supply.
SDC-150A can be controlled either digitally via RS-232 interface or manually using jumpers and trimpots (stand-alone mode). Base interface is RS-232 (RS-485 is available as an option). Simple PC software is supplied together with the controller.
The module could be synchronized internally, when pulses are generated according to the internal clock, or externally, when pulses with user fixed width are triggered by external synchronization signal.
The cooling, when needed, is performed through the heatsink attached to the bottom surface.
