Abstract

C20H18N2O2 nonlinear optical crystal and preparation method and application thereof. The crystal does not have a center of symmetry, belongs to an orthorhombic system, and has space group Pna21 and cell parameters as below. The crystal can be grown by a spontaneous crystallization evaporation method and a spontaneous crystallization cooling method, has the characteristics of fast growth and low cost; and high-quality crystals with large size are easy to grow. The obtained C20H18N2O2 crystal has the advantages of large nonlinear optical effect, powder-fold frequency effect intensity of 2-3 times OH1, chemical stability and no deliquescence, suits the need of infrared band laser frequency conversion, and can be used to produce non-linear optical device, such as a device which uses at least one beam incident electromagnetic radiation passing through at least one C20H18N2O2 nonlinear optical crystal and generates at least one bundle of output radiation with frequency different from that of the incident electromagnetic radiation.

Description

Technical field [0001] The present invention belongs to the field of crystals and preparation and application, and particularly relates to C 20 H 18 N 2 O 2 Non-linear optical crystal and its preparation method and use. technical background [0002] The science of studying the nonlinear optical effects and applications of matter under the action of strong coherent light is called nonlinear optics. Non-linear optical effects mainly include frequency doubling, sum frequency, difference frequency, optical parametric oscillation, etc. Crystals with nonlinear optical effects are collectively referred to as nonlinear optical crystals. Non-linear optical crystals can be used to make various harmonic generators, optical parametric amplifiers and other non-linear optical devices. The laser frequency conversion is realized through non-linear optical devices, thereby broadening the wavelength range of the laser and making the laser more widely used. According to the different application b...
