Dual-wavelength laser device

Abstract

The invention provides a dual-wavelength laser device, and the device comprises a pumping unit, a reflection unit, a first coupling unit, a second coupling unit, a semiconductor laser output unit andan optical fiber laser output unit; the pumping unit is used for emitting a light source, and the two different output ends of the reflection unit are respectively connected with the first coupling unit and the second coupling unit; the reflection unit can reflect and / or transmit the light beam, and the semiconductor laser output unit can gain the light beam output by the first coupling unit intosemiconductor laser and output the semiconductor laser, so that the dual-wavelength laser device can output the semiconductor laser; the fiber laser output unit can gain the light beam output by the second coupling unit into fiber laser and output the fiber laser. According to the invention, the two laser output units share the same pumping source, and the reflection unit is provided with two different output interfaces with a transmission output end and a reflection output end; therefore, the same equipment can output two kinds of laser with different wavelengths, and the application occasions of the laser device are improved.

Description

【Technical field】 [0001] The invention relates to the field of laser processing, in particular to a dual-wavelength laser device. 【Background technique】 [0002] In the current laser processing industry, fiber lasers or semiconductor lasers are usually selected as processing light sources for different materials to achieve welding, cutting, drilling, and marking of metal and non-metal materials. At the same time, semiconductor lasers and fiber lasers can also be combined as processing light sources to achieve better processing effects than single lasers, thus adapting to the needs of various product lines. However, in the laser devices in the related art, each laser can only be adapted to specific materials for processing. When there are a large number of product lines, it is often necessary to prepare fiber lasers and semiconductor lasers and supporting cooling systems at the same time and carry out independent control, which leads to equipment Costly. 【Content of invent...
