Problems solved by technology
The output end of the laser generator is directly connected to the standard connector. Since the aperture of the output end is often larger than the aperture of the connector, part of the laser light (A, C) will irradiate on the insulating rubber sheath at the connection between the optical fiber and the standard connector, such as Figure 4 As shown, with the prolongation of use time, the insulating rubber sheath at the connection between the optical fiber and the standard connector will be burned, resulting in additional cost loss

The invention discloses an anti-burning joint for laser transmission and a laser coupler with the joint and belongs to the laser transmission technical field. The anti-burning joint for the laser transmission comprises a transition tube; two sides of the transition tube are respectively provided with a joint base and a screw, wherein the joint base is integrally machined with the transition tube and is used for connecting a laser generator, and the screw is connected with a standard optical fiber joint; a through hole into which laser can be inputted is formed in the joint base; a small hole for interrupting the laser transmission so as to prevent the laser transmission from burning an optical fiber is formed in the transition tube; the diameter of the small hole ranges from 0. 6 to 1mm; and a plugging hole which is in sleeving connection the standard optical fiber joint is formed in the screw. With the anti-burning joint of the invention adopted, laser can be transmitted to the optical fiber, and the optical fiber will not be burnt by the laser, and therefore, cost loss can be reduced.
Description
technical field [0001] The invention relates to the technical field of laser transmission, in particular to a burn-proof joint for laser transmission and a laser coupler with the joint. Background technique [0002] The development of laser not only revives the ancient optical science and optical technology, but also promotes the emergence of many new industries. Laser can enable people to effectively use the advanced methods and means they currently have, and promote the improvement of productivity. Therefore, laser technology is an important trend in today's industrial development. In recent years, fiber lasers have become one of the research hotspots in the field of modern lasers due to their advantages of good beam quality, high conversion efficiency, small size, light weight and simple thermal management, and have promoted the application of laser technology from optical communication to laser Processing, laser marking, laser detection, image display, bioengineering a...
