We report on demonstration of the kW average power,100Joule-class,high-energy,nanosecond pulsed diode-pumped solid-state laser,DiPOLE100.Results from the first long-term test for amplification will be presented, the system was operated for 1 hour with 10ns duration pulses at 10Hz pulse repetition rate and an average output energy of 105J and RMS energy stability of approximately 1%.The laser system is based on scalable cryogenic gas-cooled multi-slab ceramic Yb:YAG amplifier technology.The DiPOLE100 system comprises three major sub-systems,a spatially and temporally shaped front end,a 10J cryo-amplifier and a 100J cryo-amplifier.The 10 J cryo-amplifier contain four Yb:YAG ceramic gain media slabs,which are diode pumped from both sides,while a multi-pass architecture configured for seven passes enables 10J of energy to be extracted at 10 Hz.This seeds the 100J cryo-amplifier,which contains six Yb:YAG ceramic gain media slabs with the multi-pass configured for four passes.
