Abstract
In a three-mirror optical resonator, solid state laser, the gain member is a thin slab, such as Nd:glass, disposed at Brewsters angle to minimize insertion loss. The gain slab is disposed at a beam waist in a confocal arm of the optical resonator. Optical pumping radiation from a laser diode source is focused through one of the concave mirrors of the confocal arm of the resonator into the gain slab. The second arm of the resonator is defined between a planar mirror and one of the confocal mirrors. An acousto-optic mode-locking modulator is disposed in the collimated beam region of the resonator proximate the planar mirror. Additional pumping diodes pump collinearly through the other confocal mirror for higher power operation. The slab is rotated and translated to average thermally induced stress and de-focusing effects.
