Description

technical field [0001] The invention relates to an anti-interference and highly stable cavity-empty laser and an installation method thereof, belonging to the technical field of lasers. Background technique [0002] In the actual application of lasers, factors such as mechanical disturbances and changes in ambient temperature will disturb the components in the resonant cavity, causing the laser to deviate from the optimal state, resulting in changes in the output power and output beam direction of the laser. It may even cause the laser to fail to work. This then limits the application of lasers in complex environments (such as airborne or spaceborne). Therefore, when designing lasers for such purposes, the anti-interference design of the laser and the design of the resonant cavity structure with high stability must be considered comprehensively. Contents of the invention [0003] In order to solve the problems in the background technology, the present invention provides ...
