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
