Abstract

The invention belongs to the field of nonlinear optics technology, and specifically relates to a nonlinear optical effect demonstration device, which includes a laser generating module and a medium; the laser generating module includes a laser generator, a connection plate, a support seat and a stable base; the laser generator is installed On the top of the connection plate; the connection plate is installed on the top of the support seat, a rotating torsion spring is connected between the inner wall of the connection plate and the top of the support seat, and the baffle is fixed on the inner wall of the connection plate; There is a set of right-angle grooves, and a rotating block is hinged in each right-angle groove, and rubber hoses are fixed at the positions corresponding to the four rotating blocks on the wall thickness of the top of the support seat; one side of the rotating block is glued to the tube wall of the rubber hose ; The laser generator is used to emit the first laser beam. The invention can adjust the included angle between the two laser beams, and adjust the intersecting area or volume of the two laser beams, which is beneficial to obtaining accurate data through multiple comparison demonstrations and improving the demonstration quality.

Description

technical field [0001] The invention belongs to the technical field of nonlinear optics, in particular to a nonlinear optical effect demonstration device. Background technique [0002] A branch of modern optics, which studies the nonlinear phenomena and applications of media under the action of strong coherent light. The study of nonlinear optics is of great significance to the development of laser technology, spectroscopy, and material structure analysis. Commonly used second-order nonlinear optical crystals include potassium dihydrogen phosphate (KDP), ammonium dihydrogen phosphate (ADP), potassium dideuterium phosphate (KD*P), barium sodium niobate, etc. In addition, many third-order nonlinear optical materials have been discovered. [0003] There are also some technical solutions for nonlinear optical demonstrations in the prior art. For example, a Chinese patent with application number 2013101883074 discloses a nonlinear optical effect device, including laser stacks, ...
