ABSTRACT:
A high power diode pumped laser is disclosed which has at least one resonator mirror and an output coupler. At least one laser crystal with strong thermal focussing properties is included. The laser includes at least one diode pump source supplying a pump beam to the laser crystal, producing a thermal lens in the laser crystal. The combination of the laser crystal, thermal lens, resonator mirrors and output coupler create a confocal-to-concentric resonator. An output beam is generated, which may be polarized. Further, a Q-switch may be included in the resonator, particularly when the laser crystal is Nd:YAG.
