Paper Abstract

Nanosecond laser pulses can be controlled using fast electronics and fast EOM modulators. Its usefulness has been proven in high density plasma physics, avoidance of Brillouin scattering, laser peening, laser amplification in OPCPA among others. We present an active feedback loops between the end of a regenerative amplifier and the arbitrary waveform generator that modulates its seed. We explore several algorithms and several pulse shapes, exploring the difference between them and the optimal parameters for each, finding a robust solution. The method applied here can be used to obtain any pulse shape.
