We have developed a diode-pumped, cryogenic-cooled Yb:YAG regenerative amplifier employing gain-narrowing. In the regenerative amplifier, a seed chirped-pulse was not only amplified but also temporally compressed, which generated the picosecond output pulses with 8-mJ of energy without a pulse compressor.
