AI Technical Summary

Problems solved by technology

For example, the birefringence of LBO and CBO 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 However, CLBO is extremely deliquescent and difficult to achieve commercial application; KBBF is difficult to obtain crystals with a large c-direction thickness due to its severe layered growth habit

[0002] technical background [0003] 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 lase...
