Abstract

The invention relates to a neodymium-doped bismuth zinc borate self-frequency-doubling crystal material, a cut shape and a preparation method and application thereof. The growth of NdxBi2-xZnB2O7 crystals with different doping concentrations is carried out by adopting a kyropoulos method and replacing Bi < 3 + > with an activated ion Nd < 3 + >. The invention also provides an application of the NdxBi2-xZnB2O7 crystal, employs semiconductor laser pumping with the central wavelength of 808nm, and the laser and nonlinear optical properties of the NdxBi2-xZnB2O7 crystal are utilized to obtain self-frequency doubling green light output with the output wavelength of 533nm. The laser has the advantages of compact structure, small size, high conversion efficiency, long service life, low cost, highthermal conductivity and the like, and can be used for high-power lasers.

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 ...
