Description

Technical field [0001] The invention relates to the field of optical element laser damage testing, in particular to a multi-wavelength laser damage testing and analysis system for optical elements. Background technique [0002] The high-power laser driver is required to work stably for a long time, or the performance of the system does not significantly decrease. However, after the optical components in the system are irradiated by high-power lasers, it is easy to cause component damage. This kind of damage will continue to develop under the action of subsequent laser pulses, affecting the beam output quality of the high-power laser driver. At the same time, the modulated laser pulse will cause damage to subsequent optical components, and in severe cases, the entire system will be paralyzed. The anti-laser damage characteristics of optical components will directly affect the design of the entire system and the performance of the system. Therefore, the problem of laser damage to ...
