Description

technical field [0001] The invention relates to the technical field of nonlinear optical crystals. More specifically, it relates to a yttrium-rubidium borate compound, a yttrium-rubidium borate nonlinear optical crystal, a preparation method and an application thereof. Background technique [0002] With the advancement of science, lasers with different wavelengths are in great demand in national defense, medical treatment, communications, lithography and laser processing and other fields of national economy and people's livelihood. Among them, frequency doubling technology is a method often used in the laser field to change the laser output wavelength. It often uses crystals with nonlinear optical effects to make nonlinear optical devices, and places the device in front of the laser beam to convert the frequency of the laser generated by the laser, thereby obtaining more useful wavelengths of laser light. [0003] At present, the commonly used nonlinear optical crystals ma...
