Abstract

An electronic control system, developed for power conditioning of a picosecond Nd:YLF-Nd:glass laser oscillator-amplifier chain is described, The system generates charging and firing signals required for a commercial picosecond oscillator operated in a repetitive mode, and also carries out a charging and firing sequence of external amplifiers for single-shot operation. The system also controls a mechanical shutter to selectively pass a laser pulse from the oscillator for subsequent amplification. The laser chain includes a Faraday isolator incorporated with a safety check. A control signal is generated by this unit when conditions suitable for a sufficient level of isolation are achieved, and the same is used for gating the oscillator pulse. Good synchronization is confirmed from the measurements of amplifier gain as a functionof the relative time delay in firing of different stages. The electronics developed is simple and modular, with sufficient scope for expansion of the system, and resistant to electromagnetic interference.
