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

摘要

A diode-pumped Nd:fluorophosphate regenerative amplifier was developed. Chirped seed pulses were amplified to 24 μJ at repetition rates to 1 kHz and to 5 μJ at a 10-kH↓(z) repetition rate. On compression. 850-rs 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. #1997 Optical Society of America
