Description

technical field [0001] The invention relates to a measuring device, in particular to a device for measuring optical properties of materials under strong laser conditions. Background technique [0002] At present, domestic test materials use laser spectrum analyzers, laser spectrophotometers, etc. for the properties of laser transmittance, reflectivity, and absorptivity. The power is only at the milliwatt level. and absorbent equipment. The high-power laser refers to a laser with a power greater than 40W. [0003] At the same time, because the traditional measurement devices for optical properties of materials are all measured under low-power laser conditions, they can only test the transmittance, absorption rate and other properties of the material, and cannot conduct research on the damage mechanism of high-energy lasers and test the anti-laser ability of materials. Contents of the invention [0004] In view of this, the present invention provides a device for measuring...
