The invention discloses a resonant component of a laser, and a debugging method for the laser and the resonant component. The resonant component of the laser includes: a reflection mirror; an output mirror, which is coaxial with the reflection mirror and arranged at intervals; a first optical element, located between the reflection mirror and the output mirror, between the central axis of the first optical element and the central axis of the output mirror The angle between them is greater than 0°. By adopting the invention, the stray light near the far-field laser spot can be effectively removed, and the ranging accuracy and indication effect can be improved. At the same time, it can reduce the requirements on the surface processing accuracy of optical components to a certain extent, such as the parallelism and coaxiality of the front and rear surfaces of optical components, etc., which can greatly reduce the procurement cost of components, and is suitable for mass production of lasers.
Description
technical field [0001] The invention relates to the field of lasers, in particular to a resonant component of the laser, and a debugging method for the laser and the resonant component. Background technique [0002] The laser oscillation formed by the resonant component of the laser exists between the output mirror and the reflector. The other optical components of the resonant component except the output mirror and the reflector only act as a light-through window and do not participate in the laser oscillation. Since there are residual reflections on the surface of other optical components except the output mirror and reflector of the resonator component, and due to the lack of parallelism between the actual assembly and the processing of the front and rear surfaces of the optical components, it is inevitable that the residual reflection light on the surface of each optical component is related to the output The laser has a small angle. When there are many optical elements...
