Problems solved by technology

However, the current 10,000-watt-level laser output head mostly adopts the foreign LK-D structure, which is bulky and complex in structure. Especially when cutting high-reflectivity materials or welding, it often burns the optical fiber or burns the laser due to the strong return light. Case

Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the drawings and embodiments.

[0030] The “front” and “head” that may be mentioned in the present invention refer to the side of the output end in the laser output direction, and the “rear”, “end” and “tail” that may be mentioned in the present invention refer to the input end in the laser output direction. side.

[0031] The present invention provides a laser, which is specifically a fiber laser, which includes a figure 1 The laser output head 100 shown. The laser and the laser output head 100 are particularly suitable for the output of 10,000-watt high-power lasers.

[0032] Such as figure 2 As shown, the laser output direction in the laser output head 100 is from lower left to upper right, and the return direction is opposite. The laser output head 100 includes a water-cooled component and a laser energy transfer component installed in the water-cooled component. The water-cooled component cools...

Abstract

A laser and a laser output head (100). The laser output head (100) comprises a water-cooling assembly internally mounted with a laser energy transfer component and performing water cooling on the laser energy transfer component to dissipate heat. The water-cooling assembly comprises a housing (1) and a water-cooled member (13). The water-cooled member (13) is accommodated in the housing (1). The outer wall of the water-cooled member (13) is formed with cooling grooves (131, 132) of a double helix structure. The two cooling grooves (131, 132) are communicated at one end, and a water inlet port and a water outlet port are respectively formed at the other end. The water-cooled member (13) is abutted against and fastened to the inner wall of the housing (1) by means of a convex portion (130), forming the cooling grooves (131, 132), on the outer wall of the water-cooled member (13). The contact area between the cooling water and the water-cooled member (13) is increased, and the heat dissipation efficiency can be improved so that the heat is dissipated timely, and the problem of burning an optical fiber (21) or the laser can be effectively prevented due to the strong return light.

Description

Technical field [0001] The invention relates to the technical field of laser equipment, in particular to a 10,000-watt high-power laser and its laser output head. Background technique [0002] With the increasing popularity of lasers in higher power cutting, welding, etc., the demand for 10,000-watt high-power laser output heads is increasing. However, most of the current 10,000-watt laser output heads use the foreign LK-D structure, which is bulky and complex, especially when cutting high-reflectivity materials or welding, it often burns fiber or laser because of strong back light. Case. Summary of the invention [0003] In order to solve the above technical problems, the present invention provides a high-power laser and its laser output head. By arranging a water cooling element with a cooling groove with a double spiral structure, the contact area between the cooling water and the water cooling element is increased, thereby improving heat dissipation The efficiency ensures ti...
