✦ Synopsis

This work describes the experimental results obtained on the Cr4+: YAG crystal used as a passive Q-switch in Nd:YAG lasers. In addition, the combination of a Cr 4+ : YAG passive Q-switch with an acousto-optical Q-switch operating simultaneously in one cavity was investigated.

More than 180 W average output in the passive Q-switched mode was obtained with the Cr4+ : YAG crystal. The pulseto-pulse stability was better than 1%. A mode selection occurred when the laser system operated near threshold.

The realization of high repetition rate passively Q-switched monolithic microlaser is a challenge since a decade. To achieve this goal, we report here on the first passively Q-switched diode-pumped microchip laser based on the association of a Nd:GdVO 4 crystal and a Cr 4+ :YAG saturable absorber. T

We report on the passively Q-switched mode-locking of a quasi-cw (QCW) diode pumped Nd:GdVO 4 laser with Cr 4+ :YAG saturable absorber. We show that by using the QCW pumping high quality Q-switched mode-locking can be easily obtained in the laser even with a simple two-mirror laser cavity configurat
