Problems solved by technology

Because the detection area of ​​the laser power meter will receive the laser with continuous high energy and power density, the laser optical power meter will be protected by heat dissipation and cooling methods, such as water cooling, TEC (Thermo Electric Cooler), and the use of semiconductor materials. Ertier effect), etc., especially the 10,000-watt-class laser power meter is expensive, and needs multiple ways to protect, but the existing heat dissipation and cooling methods are all passive protection methods
When the diameter of the emitted laser spot is relatively small, the local area of ​​the optical power meter will continue to receive the laser with high energy power density. If the laser cannot be stopped in time to emit laser light, it will lead to excessive accumulation of laser energy per unit time in the detection area of ​​the laser power meter. burnt out, resulting in serious economic losses

Embodiment 3

[0068] This embodiment implements a 10,000-watt laser power meter protection device.

[0069] Existing 10,000-watt laser power meters are expensive, and generally use water cooling to dissipate heat. There are also methods to protect the laser power meter by detecting the water flow to control the laser light output. However, these methods are passive protection methods. When the detection area of ​​the laser power meter continues to receive high-energy power density laser light, the laser power meter can only passively receive the energy of the laser, and cannot judge whether the continuous reception of high-energy laser will cause power The meter was burnt out. In view of the above problems, it is urgent to design a device and method to protect the laser power meter and avoid heavy losses. In this embodiment, the temperature of the detection area of ​​the laser power meter is monitored in an active real-time manner, and the laser light output is controlled according to the ...
