Laser output end of fiber laser

Abstract

The invention provides a laser output end of a fiber laser. The laser output end comprises an optical fiber, a pipe body, a first joint and a second joint, wherein the first joint and the second joint are fixed at two ends of the pipe body respectively; the optical fiber is arranged in the pipe body in a penetrating manner and extends to the first joint and the second joint; a first temperature switch is arranged in the first joint; a second temperature switch is arranged in the second joint; the first temperature switch is electrically connected with the second temperature switch through a wire; and the first temperature switch and the second temperature switch open or close the laser output end of the fiber laser according to the temperature of the laser output end of the fiber laser respectively. Therefore, the laser output end of the fiber laser provided by the invention is controlled to be opened or closed by the sensitivity of the temperature switches on the temperature; the condition that a connection light path is in a normal state is ensured; and the condition the fiber laser is safe and reliable to use is ensured.

Description

Technical field [0001] The invention relates to a laser output end of a fiber laser. Background technique [0002] As the application of laser technology in industry becomes more and more extensive, it is a higher requirement for high-power fiber lasers to be put into production flexibly and quickly under different circumstances. [0003] The laser output end provides high-power optical energy transmission for high-power fiber lasers. In practical applications, the laser output end has more and more flexible and efficient processing requirements for the flexible and rapid distribution and switching of optical optical paths, which provides convenience and possibilities for modular high-power fiber lasers. [0004] However, due to the manufacturing process and other reasons, the optical fiber has different axis, which will lead to misalignment, and the final laser light source is inconsistent, which affects the product quality. The fiber core diameter is generally several hundred micr...
