Abstract

The authors have stabilized the frequency of a cw, lamp-pumped, mode-locked Nd:YLF oscillator. The output pulse duration is 50 ps and, simultaneously, the mode jitter is less than 25 kHz relative to a stable, high-finesse Fabry-Perot. The frequency shifts and broadening of the oscillator modes caused by pulsed amplification in a flashlamp-pumped Nd:glass rod with a gain of 100 have been measured. Broadening and frequency shifts on the order of 10 kHz are induced by the amplifier. The changing population of the active transition in the amplifier is the dominant source of the frequency shifts. For frequency-stable amplification, significant saturation of the gain medium must be avoided.
