Abstract

The invention provides an output head with Raman filtering. The output head with the Raman filtering function comprises a mounting support, an output end, a Raman filter and a Raman filter, wherein the mounting support is provided with an external thread bushing; the heat dissipation mechanism is mounted on the mounting support; and the connecting joint is mounted on the axis of the mounting support, an internal thread bushing is arranged on the connecting joint, and the internal thread bushing is mounted on the external thread bushing in a threaded manner. According to the output head with the Raman filtering function, the Raman grating installed outside the connector is integrally installed between the installation support and the connecting connector, the connecting connector can conveniently filter Raman light reflected by a cable in a closed mode, the Raman light and reflected light can be better filtered, a laser device is safer in use, and the service life of the laser device is prolonged. And the welding problem of a plurality of devices is reduced, so that the process is simplified.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to an output head with Raman filtering. Background technique [0002] With the continuous development of society and the increasing demand for cutting technology, the use of fiber laser technology has become the development trend of cutting in the future. Fiber laser cutting has become a trend in the general metal processing industry, and is widely used in sheet metal metal processing, etc. , As the thickness of the processed sheet in the market demand is getting thicker and thicker, the requirements for the laser and laser processing head, the core components of the laser processing equipment, are becoming more and more stringent. [0003] In the process of optical fiber installation and use, it is necessary to use the optical fiber output head to connect the laser and the laser head. Its importance is self-evident, because the traditional QBH cooling method cannot reduce the large ...
