Solid-state lasers for generating high-energy, high-energy, and high-power laser beams

摘要

The present invention relates to solid state lasers for generating high energy, high energy and high power laser beams. More particularly, the present invention relates to a solid-state laser capable of generating a laser beam having a high energy and a high output at a high repetition rate and performing optical alignment easily. The solid laser of the present invention comprises a first beam size adjustment means 93); A polarization beam splitter 4; A first linearly polarized light rotating means 5; First light splitting means (7); A first laser amplifying means 11 configured by connecting a plurality of laser amplifiers including an amplifier 8, a lens 9 and a stimulated Brillouin scattering cell 10 serving as a phase conjugate mirror in parallel; A second linearly polarized light rotating means 12; A second light splitting means (13); And a second laser amplifying means 17 including a plurality of laser amplifiers including an amplifier 14, a lens 15 and a guided Brillouin scattering cell 16 serving as a phase conjugate mirror connected in parallel, (18) are connected in series. The solid-state laser according to the present invention can generate a laser beam having an infinitely large output and energy in a small space with a high repetition rate, and has an effect of optically aligning easily.
