Problems solved by technology

For example, the birefringence of LBO is relatively small, and the quadrupling output of 1064nm wavelength laser cannot be realized; the birefringence of BBO is relatively large, and there is a photorefractive effect when used for quadrupling output of 1064nm wavelength laser, which limits its Output power and beam quality; while CLBO is extremely deliquescent and difficult to achieve commercial applications; KBBF is difficult to obtain crystals with a large c-thickness due to its serious layered growth habit

Description

technical field [0001] The present invention relates to a kind of Cs 2 LiPO 4 Compound, Cs 2 LiPO 4 Nonlinear Optical Crystals, Cs 2 LiPO 4 Crystal preparation method, Cs 2 LiPO 4 Use of crystals for making nonlinear optical devices and containing Cs 2 LiPO 4 Optical devices for nonlinear optical crystals. Background technique [0002] The nonlinear optical effect of crystal refers to such an effect: when a beam of laser light with a certain polarization direction passes through a nonlinear optical crystal in a certain direction, the frequency of the beam will change. Crystals with nonlinear optical effects are called nonlinear optical crystals. Using the nonlinear optical effect of crystals, nonlinear optical devices such as second harmonic generators, up-down frequency converters, and optical parametric oscillators can be made. The all-solid-state laser using nonlinear optical crystals for frequency conversion is a development direction of lasers in the future, ...
