Description

technical field [0001] The invention relates to a neodymium-doped zinc-bismuth borate self-frequency doubling crystal material, a cutting type, a preparation method and application thereof, and belongs to the technical field of laser and nonlinear optics. Background technique [0002] Functional crystalline materials are an important basis for optoelectronic devices. At present, functional crystals are developing in the direction of functionalization, compounding and integration of materials and devices. When two or more functional properties act on the same crystal, a composite functional crystal material is formed. The laser self-frequency doubling crystal is an important composite functional crystal. It uses the nonlinear optical effect of the matrix crystal to convert the stimulated emission of the activated ions into the second harmonic, so that it has the stimulated emission performance of the laser crystal at the same time. And the frequency doubling performance of ...
