Abstract

Recently few cycle pulses with an ultrahigh peak power and a high average power have been actively developed by using a conventional Ti:sapphire system and an optical parametric chirped-pulse amplification (OPCPA) system. A powerful pump source is enthusiasmly desired in nano- and pico-seconds for Ti:sapphire and OPCPA, respectively. A "GENBU (Generation of ENergetic Beam Ultimate)"-laser has been conceptually designed for peta-watt peak power at 100 Hz by using the broadband OPCPA technique. A 100 J pulse energy is necessary as a pump source and a diode-pumped solid-state laser is one of the most promising system, which uses novel technologies of a cryogenic Yb: YAG and an active mirror amplification scheme. A feasibility of the pump source has been studied at sub-joule pulse energy to show its viability of this new laser system. A master-oscillator power-amplifier (MOPA) system has been developed at 150 mJ at 100 Hz in 10 ns.
