This laser emission system adopts an integrated design with a high-strength black metal housing as the main body, equipped with a high-precision optical emission window and stable support structure. The system integrates a laser source, beam control and aiming calibration modules, featuring high pointing accuracy and stable output performance. The compact mechanical structure provides both protection and heat dissipation, suitable for various application scenarios. It enables directional emission and precise control of laser beams to meet the requirements of scientific research, industrial or testing fields.

The laser emission system is an optomechatronic integrated transmitting unit integrating laser driving, beam shaping, collimation and beam expansion, and pointing control. It converts electric energy into high-quality, stably and controllably laser beams and transmits them directionally to the target area, serving as the core front end of lidar, laser ranging, laser communication, laser detection, laser processing and photoelectric reconnaissance systems. ### I. Working Principle The system consists of a laser, driving circuit, collimation and beam expansion assembly, optical adjustment mechanism and control module: The driving module provides stable current/pulse signals for the laser; The laser outputs the original beam; The beam is shaped by collimating lenses, beam expanders and two-mirror/multi-mirror optical systems; Laser output with small divergence angle, high parallelism and stable pointing is realized; Power, frequency, focal length and pointing can be adjusted via the control module. ### II. Core Functions Stable light output: constant power/constant current control ensures long-term operational consistency. Beam collimation: small divergence angle prevents spot diffusion during long-distance transmission. Beam shaping: circular/linear/array spots for different application scenarios. Precise pointing: fixed-angle or scanning emission with high positioning accuracy. Protection and control: over-current, over-temperature and misoperation protection, supporting external trigger and communication control. ### III.
