โœฆ Synopsis

In this paper, we report that mode-locked operation is realized in a ashlamp-pumped Nd:YAG laser with a nearly critical stable resonator, using LiF:F - 2 color center crystal as a modulation device. A single pulse train with the energy of 25 mJ and the pulse duration of 82 ps is obtained. Both the theoretical and experimental results have shown that the mode-locked operation has resulted from kerr-lens e ect formed in combination with self-focusing within Nd:YAG and an aperture at a speciรฟc point, but not directly from the saturable absorption of LiF:F - 2 crystal.

Passive mode-locking of a pulsed Nd:YAG laser using a Cr 4+ :YAG saturable absorber was realized for the ยฎrst time in a nearly critical stable resonator containing an antiresonant ring structure. The output energy and pulse duration are 13.5 mJ and 180 ps, respectively. The recovery time and saturab
