Abstract

We report on the progress of the front end development for a 100 J, 1030 nm amplifier at ELI-Beamlines and discuss requirements for and features of the front end. A particular emphasis is placed on the use of a fiber-based nanosecond pulse generator to produce arbitrarily shaped, stable pulses. Disadvantages of using such a fiber-based seed, such as a wandering baseline, are discussed and solutions are presented. A home-built RF harmonic synthesizer is shown to be capable of controlled sub-nanosecond shaping of optical pulses.
