The main laser feature is the ability to shape output pulses temporally which is accomplished by an electro-optical modulator driven by programmable arbitrary waveform generator (AWG). The front end of Ekspla's ANL AWG laser system is comprised of a single-mode CW laser which is amplified in a fiber amplifier in the next step. Later on, AWG driven modulator transmits pulses of required temporal shape and duration which are further amplified diode pumped regenerative amplifier or all-in-fiber amplifier in order to reach energies sufficient to amplify in single-pass diode and flash lamp pumped amplifiers. Pulse shaping resolution is 125 ps, while maximum pulse length is 500 ns.

ANL series linear amplifiers are convenient solution for high energy nanosecond systems where pulses are amplified in a chain of flash lamp pumped amplification units up to required energy. During amplification spatial beam shaping is used in order to get a flat top shaped beam profile without hot spots at the system output.

Angle-tuned non-linear crystals harmonic generators mounted in temperature stabilized heaters are used for second, third and fourth harmonic generation. Harmonic separation system is designed to ensure high spectral purity of radiation and direct it to the output ports.
