Abstract

The invention relates to the technical field of lasers, and discloses an optical thin film testing method and equipment. The optical thin film testing method comprises the following steps: obtaining the laser transmittance of a to-be-tested material, wherein the to-be-tested material is plated with an optical thin film used for transmitting laser, and the laser is generated by a laser according to specified laser parameters; determining the target surface temperature when the laser acts on the optical thin film; and testing the qualification of the optical film according to the laser transmittance and the target surface temperature. Therefore, according to the method, the laser transmittance and the target surface temperature can be automatically utilized to measure the qualification of the optical thin film, the participation of human factors is reduced as much as possible, the accuracy of a measurement result is improved, and the measurement time is saved.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to an optical thin film testing method and testing equipment. Background technique [0002] In order to improve the output energy and output characteristics of the laser, and eliminate the influence of stray light in the laser on the optical components inside the laser, optical thin films are widely used in various lasers. Among them, the damage threshold of the optical film is an important factor to limit the output intensity of the laser and measure the safe operation of the laser system. [0003] In the actual damage measurement of optical thin films, various companies or scientific research institutions often use different spot sizes and different laser wavelengths according to their actual needs, combined with different damage judgment methods for measurement. The existing measurement method requires manual participation in the whole process, the degree of automation is relativ...
