Abstract

The invention relates to a system for testing optical thin film damage threshold. The system comprises a pulse laser, an attenuator, a converging lens, a window mirror, a beam splitting mirror, a total reflection mirror, an energy meter, a first image collecting device and a second image collecting device, wherein light beams emitted from the laser transmit to the converging lens after attenuation by the attenuator, the light beams converged by the converging lens sequentially pass through the window mirror and the beam splitting mirror for transmission and are reflected by the total reflection mirror and then enter into the optical thin film to be tested, the light beams reflected by the window mirror enter into the first image collecting device, the light beams reflected by the beam splitting mirror enter into the energy meter, and the second image collecting device collects image information on the surface of the optical thin film to be tested. The system for testing optical thin film damage threshold is accurate in testing result, easy to install and adjust, and wide in application.

Description

technical field [0001] The invention relates to a test system for optical components, in particular to a test system for the damage threshold of an optical film. Background technique [0002] The continuous development of laser technology makes it widely used in various fields. Accurately grasping the laser-induced damage threshold of optical thin films is particularly important for researchers and engineers in the field of intense laser research. Because there are many factors affecting laser damage, it involves a wide range of areas, and the damage mechanism is also very complicated. Therefore, high-power laser-induced optical film damage is still a hot spot that many researchers at home and abroad pay attention to. [0003] Accurate measurement of the damage threshold of laser optical thin films is a necessary condition for the study of optical components with high resistance to laser damage. The damage threshold of optical thin films is a key parameter of the thin film...
