Abstract

The invention relates to a nonlinear optical crystal of large-size sodium borate vanadium, and a preparation method and application thereof. The crystal has the molecular formula of Na3B6VO13, belongs to the rhombic system, and has the molecular weight of 392.77, the crystal size of 10-60mm multiplied by 10-60mm multiplied by 10-60mm and the Mohs hardness of 5.5; a sodium borate vanadium compound is adopted to be evenly mixed with a fluxing agent, heated until constant temperature, and cooled until saturation temperature, thus obtaining a mixed solution; seed crystal is placed into the mixed solution, and the temperature is decreased until the saturation temperature, thus obtaining the required crystal; the crystal is extracted from liquid surface, and the temperature is decreased until room temperature, thus obtaining the nonlinear optical crystal of large-size sodium borate vanadium. The nonlinear optical effect of the nonlinear optical crystal of large-size sodium borate vanadium is half of the effect of the KDP crystal, and the light transmitting wave range of the crystal is 375nm to 3000nm. The nonlinear optical crystal of the large-size sodium borate vanadium has the advantages of simple operation, low cost, large crystal size, short growth period, less inclusion, high laser damage threshold, good mechanical performance, non-easy fracture, stable physicochemical property, non-deliquescence and easy process and storage, etc. The nonlinear optical crystal of the invention can be widely used in frequency doubling conversion and nonlinear optical devices such as optical parametric oscillators, etc.

Description

Technical field [0001] The invention belongs to a nonlinear optical crystal and a growth method and application, and particularly relates to a large-size sodium vanadium borate nonlinear optical crystal and a flux crystal growth method and application. Background technique [0002] Non-linear optical crystal is a kind of crystal material with non-linear optical effects such as frequency doubling, frequency mixing, and optical parametric oscillation. Using the frequency doubling effect of the crystal, the frequency of the laser can be changed, and the wavelength range of the laser light source can be broadened, thereby obtaining a new laser light source and making the laser widely used. The all-solid-state blue-green laser system is made by using nonlinear optical crystals. It has the advantages of small size, stable light source, and low cost, and has broad application prospects. [0003] After decades of efforts by scientists from various countries, many nonlinear optical crysta...
