Abstract

Due to the limitation of its crystal characteristics, Holmium laser cannot directly produce high-power laser output. This article uses the relationship between the pulse and angular displacement of the servo motor to design a three-light path flat-flat stable cavity structure, which is adjusted by the servo motor The direction of the light path, and then realize the combined beam output laser. The I/O port output pulse sequence is generated by STM32 real-time timing to control the initial position and speed of the servo motor driver. The three-hole mirror frame is driven by the rotation of the servo motor, and the slot-type optical coupler is used for positioning, and the laser resonant cavity of each channel works independently in turn by time division multiplexing, and finally realizes the combined laser beam output.
