Abstract
The present application discloses a nonlinear optical crystal material, preparation method and application of the nonlinear optical crystal material. A nonlinear optical crystal material, whose molecular formula is GaSe; wherein the crystal structure of said nonlinear optical crystal material belongs to trigonal system, space group R3 with the lattice parameters of a=b=3˜4.2 Å, c=9˜10 Å, α=β=90°, γ=120° and Z=1. The nonlinear optical crystal material has an excellent infrared nonlinear optical performance, whose frequency-doubling intensity can reach 9.3 times of AgGaSwith the same particle size, and it meets type-I phase matching; and its laser damage threshold can reach 7.5 times of AgGaSwith the same particle size. The nonlinear optical crystal material has important application value in the frequency-converters which can be used for frequency doubling, sum frequency, difference frequency, optical parametric oscillation of laser in mid and far infrared waveband, and the like.
