Abstract

Thermal lensing effects in a cw-pumped Nd:YLF rod have been characterized, permitting the optimization of the laser resonator. In the mode-locking regime, a well-designed system generates an average output power similar to that of a typical Nd:YAG laser with, however, an increased stability and pulse durations that are significantly shorter.
