Description

Main laser feature is output of temporary shaped pulses based on electrooptical modulator driven by programmable arbitrary waveform generator (AWG). Pulse shaping resolution is 125 ps, while maximum pulse length is 10 ns. Start of the system is single mode CW laser. Then light is amplified in fiber amplifier, later AWG driven modulator transmits only required temporal shape and duration pulse which is amplified in diode pumped regenerative amplifier in order to reach energy sufficient to amplify in singly pass flash-lamp pumped amplifiers. Power amplifier is a chain of single-pass amplifiers where pulse is amplified up to required energy. During amplification spatial beam shaping is used in order to get flat top shape at the output. The second harmonic generator is based on angle tuned nonlinear crystal placed in a heater.
