Problems solved by technology

However, for such a square device, if the absorber absorbs light insufficiently, a large amount of laser light will overflow the absorber through reflection, causing photoaging effects on surrounding devices
In addition, under the action of a high-power kilowatt or even 10,000-watt laser, the temperature distribution of the entire absorber is uneven due to the large amount of laser power absorbed by the liquid in the initial stage, and the liquid will be heated to boiling rapidly, which may cause liquid overflow and absorber burst. Waiting for unsafe hazards

Abstract

The invention provides an active cooling high-energy laser absorbing device based on liquid absorption. According to the scheme, the active cooling high-energy laser absorbing device comprises a laser beam expander, a tapered pool, a cooling water pipeline and a supporting member, wherein the tapered end of the tapered pool is disposed on the supporting member, the laser beam expander is disposed on the bottom surface of the tapered pool, the cooling water pipeline is disposed between the supporting member and the tapered pool, and the absorption liquid is injected into the tapered pool. The active cooling high-energy laser absorbing device can absorb high-energy laser in a steady, reliable and safe manner, can be widely applied, and can be continuously used for a long period of time.

Description

technical field [0001] The invention relates to the application field of lasers, in particular to an active cooling high-energy laser absorption device based on liquid absorption. Background technique [0002] Since the first laser came out in 1960, laser technology (especially high-power laser) has achieved great development and is widely used in industry, medical treatment, scientific research, national defense and other fields. With the continuous improvement of laser power, laser safety issues have attracted more and more attention. High-power lasers act on the human body, causing local skin burns in mild cases, and blindness in severe cases. For laser safety, countries around the world have issued many standards to guide laser users on how to safely operate lasers, especially high-energy lasers. [0003] During the use of the laser, it may be necessary to stop the laser output at any time according to the actual situation. It is generally realized by arranging an opt...
