Abstract
The invention provides a compactly built solid state laser, which can be pumped by high power semiconductor laser diodes and uses two or more laser crystals as the laser gain or amplification media, which crystals can also contain the resonator mirrors. As desired per the invention, linear, monolithic folded or ring-shaped laser resonators can be formed to provide very efficient production of frequency doubled laser radiation.
Claims25
A compact solid-state laser system having a resonator which is formed linearly, folded or ring-shaped comprising,
- a) at least two laser crystals mounted in optical opposition,
- b) means optically associated with each of said crystals to pump said crystals to generate a laser beam therebetween and
- c) partially reflective means, mounted optically between at least a pair of said crystals, for outcoupling a portion of said laser beam generated by said crystals and for resonating the remainder of said beam between said crystals.
