Abstract

The invention discloses a C15H11NO2S nonlinear optical crystal which does not have a symmetry center, and belongs to a monoclinic system. The space group is Pc, and the cell parameters are as follows: a=9.466 A', b=6.060 A', c=11.771 A', alpha=gamma=90 degrees, beta=106.248 degrees, Z=2, and V=648.3 A'<3>; a spontaneous crystallization volatilization method, a falling temperature method and a seed crystal method can be adopted for crystal growth, the characteristics of high growth rate and low cost are achieved, and the large-size and high-quality crystal can easily grow; the obtained C15H11NO2S crystal powder has the double-frequency effect strength being 1-2 times of OH1, is stable in chemical property, does not deliquesce, meets needs of infrared band laser frequency conversion, and can be used for manufacturing a nonlinear optical apparatus; the apparatus comprise a device which can enable at least one beam of incident electromagnetic radiation to pass through at least one piece of C15H11NO2S nonlinear optical crystal so as to generate at least one beam of output radiation of which the frequency is different from that of the incident electromagnetic radiation.

Description

technical field [0001] The invention belongs to the field of crystals and preparation and application, in particular to C 15 h 11 NO 2 S nonlinear optical crystal and its preparation method and application. technical background [0002] The science of studying the nonlinear optical effects produced by matter under the action of strong coherent light and its applications is called nonlinear optics. Nonlinear optical effects mainly include frequency doubling, sum frequency, difference frequency, optical parametric oscillation, etc. Crystals with nonlinear optical effects are collectively called nonlinear optical crystals. Various nonlinear optical devices such as harmonic generators and optical parametric amplifiers can be made by using nonlinear optical crystals, and laser frequency conversion can be realized through nonlinear optical devices, thereby broadening the wavelength range of lasers and making lasers more widely used. According to the different application bands...
