[0002] At present, the application of laser is very extensive. According to whether the laser probe is in contact with the material acted by the laser, it is divided into two working modes: contact and non-contact. The main application fields of laser include industry, medical treatment, commerce, scientific research, information, etc. Among them, the application of laser in the commercial field includes laser marking and laser engraving, etc. Laser marking can be used for product identification and anti-counterfeiting. It precisely marks the surface of the material by controlling the laser beam. In order to protect the safety of the laser transmitter head and the user, the laser marking machine is usually equipped with an external cover to protect the laser head. However, during the continuous operation of the laser marking machine, the laser transmitter head is prone to overheating and needs to be shut down for heat dissipation before it can continue to work.
