Abstract

Currently, the development of lasers operating in the mid-infrared (MIR), is of greater interest for a wide range of applications. All pump diodes are supplied with silica fibres. Together with the high water absorption of fluoride fibers catalyzed by high pump power density, this makes it impossible to use external butt-coupling techniques to inject pump source radiation into a fluoride fiber. We proposed and implemented the idea of the side-polished (D-shaped) fiber-based pump combiner. The pump combiner with 75% efficiency has been developed. The TEC system of cooling and heating with temperature feedback allowed for a reduction in losses in the system from 1.32 dB to 1.02 dB.
