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, ...
