Diode-pumped Nd:glass kHz regenerative amplifier for subpicosecond microjoule level pulse

Summary form only given. Diode-pumped lasers are being developed as cost effective and compact systems. To date, most of the research on direct diode-pumped femtosecond sources has concentrated on mode-locked oscillators. Recently, however, a diode pumped regenerative laser amplifier was reported pushing direct diode pumped amplifiers into the femtosecond regime. Nd:glass, with a strong absorption band at 800 nm, would be a good material for a diode-pumped amplifier system.
