A high-stability laser engine is an integrated core functional unit consisting of a light source module, temperature control system, drive circuit, and optical calibration component. It achieves long-term stability of laser output parameters through multi-dimensional coordinated control. Compared with ordinary lasers, its core difference lies in the adoption of an active intervention mechanism to offset environmental interference, ensuring precise control of wavelength, power, and beam quality during long-term operation.
