Title: Diode-pumped Nd:glass kilohertz regenerative amplifier for subpicosecond microjoule level pulses

Journal Article · · Applied Optics
OSTI ID:664447

A diode-pumped Nd:fluorophosphate regenerative amplifier was developed. Chirped seed pulses were amplified to 24 {mu}J at repetition rates to 1 kHz and to 5 {mu}J at a 10-kHz repetition rate. On compression, 850-fs pulses were obtained. White-light continuum generation was observed when these pulses were focused into a glass sample. Furthermore, based on a rate equation analysis, the effects of the gain material lifetime on the pulse energy at high repetition rates are discussed. {copyright} 1997 Optical Society of America
