The PLPS programmable laser pulse shaper is a user-programmable high voltage digital to analog converter driven by fast RAM and controlled by an embedded microcontroller. The PLPS is supplied with a modulator which may be driven between maximum transmission and maximum extinction under software control. The sample rate is nominally 150MHz and the electrical rise-time at the Pockels cell is nominally 20 ns.
The PLPS is designed to compensate for gain depletion in long pulse laser amplification systems. The maximum electrical pulse duration is 10 μs, which corresponds to nominally 1.5 kV samples. The maximum output voltage is >700 V which corresponds to 100% gain modulation at 1.3 μm with the modulator provided.
