Abstract

Frequency-doubling conversion efficiency test device for centrosymmetric material micro-nano structure devices, consisting of laser, collimator beam expander system, polarizer, incident light barrier, alignment microscope, receiving platform, horizontal angle rotation platform, multi-dimensional adjustment platform, frequency-doubling light It is composed of optical filter, mask, laser power meter and large bottom platform. The laser emitted by the laser passes through the collimator beam expander system, polarizer and incident light bar, and is observed by the alignment microscope through the horizontal angle rotation stage and the multi-dimensional adjustment stage to adjust the alignment. The frequency-doubled light that is injected into the sample under test and doubled by the sample to be tested is received by the laser power meter and measured to show the light intensity value of the frequency-doubled light, and then compared with the light intensity value detected when the sample under test and the filter are not placed. Compared with the light intensity value, the frequency doubling conversion efficiency can be obtained. The position of the sample to be tested is quickly adjusted by the multi-dimensional adjustment table and the horizontal angle rotation table, which is convenient to adjust, high in measurement accuracy, and easy to apply and popularize.

Description

technical field [0001] The invention relates to a device for testing the frequency doubling conversion efficiency of a micro-nano structure device of a central symmetry material, and belongs to the technical field of testing the conversion efficiency of a nonlinear device. Background technique [0002] With the continuous advancement of optical laser technology and microstructure processing technology, nonlinear optical devices not only used in laser frequency doubling and other fields have been continuously produced and widely used, but also nonlinear optical devices composed of centrosymmetric material micro-nano structures have been produced. , can also produce frequency doubling effects. The emergence of micro-nano structures with optical nonlinear effects in centrosymmetric materials enables the integration of nonlinear components such as frequency conversion and other photonic devices, such as lasers, waveguides, and detectors, on the same linear material substrate to ...
