AI Technical Summary

Technical Problem

During use, existing carbon dioxide lasers may experience issues such as damage to the acousto-optic modulator or incorrect parameters, resulting in a laser beam that does not meet processing requirements, leading to workpiece damage or equipment destruction.

Method used

Design a laser system with real-time monitoring and protection functions. The laser beam is split into a working beam and a detection beam by a beam splitting unit. The output power is monitored by a laser probe and converted into a voltage signal. A relay controls the on/off state of the laser based on the voltage signal to ensure that the laser is shut down in time under abnormal conditions.

Benefits of technology

It enables real-time monitoring of the laser beam, avoids damage to workpieces and equipment, ensures processing efficiency, and provides a modular upgrade path suitable for lasers of different wavelengths and power levels.
