AI Technical Summary
When adjusting the ring optical path of an external cavity large laser gyroscope, the gain tube is located inside the ring cavity, making it impossible to directly observe the beam path, which leads to difficulty in adjustment and low success rate, becoming a bottleneck restricting its engineering application.
By installing an indicator laser and a reflector on the platform, a three-mirror cavity with a missing corner, including a laser gain tube, three corner cavities and two reflectors, is constructed. The reference transmitted light spot is used to precisely guide the ring optical path, thereby realizing laser oscillation and closing the optical path.
It significantly improves the success rate and efficiency of building optical paths for large laser gyroscopes, provides a clear and well-defined dimming method, and solves the problem of cavity adjustment under the condition of built-in gain tube.
