Highly stabilized solid state lasers with directional prism reflector

摘要

A new kind of highly stabilized solid-state lasers have the ability of high anti-disalignment and unique stability. The resonator is consisted of directional prism reflector and plane output window. The biggest allowed disalignment angle of the reflector can be $POM@20, which is 2 orders of magnitude higher than plane-plane resonator. It can be certified from theoretic analysis and experimental measurements that the lasers with kind of construction not only have higher ability of anti-disalignment, but also can compensate optical distortion and inhomogeneity of all of the optical components in the resonator. It makes the optical density distribution uniform and avoids or reduces laser damage. Laser beam quality can be improved. Especially, this kind of lasers fit for the application in the situation of vibration and high power Q-switch laser output.
