In the context of continuous development in the fields of industrial manufacturing and biomedicine, 2μm fiber lasers, with their unique performance, have become key technological supports for industrial non-metal processing and minimally invasive medical applications. DoGain focuses on industry demands and relies on a strong new product and packaging platform to launch the 793nm high-power fiber-coupled module series, which is centered around high-power semiconductor laser chips. This initiative injects new momentum into the development of 2μm laser pumping technology and assists in the upgrading of high-power 2μm thulium-doped fiber laser products. The high-power 793nm pumping module launched by DoGain boasts advantages such as high reliability, high stability, and cost-effectiveness, which can broaden the application scenarios for 2μm fiber lasers and further promote technological upgrades in related industries.

The single light output power of high-power semiconductor laser chips continues to increase, and the current mainstream application has risen to 45W, but when moving towards higher power 50W, 60W or even higher power, the thermal conductivity of ceramic heat sink, which is the "heat dissipation backing" of the chip, has become a constraint, although the thermal conductivity of AlN ceramics has increased from the previous 170W/m·K to the current 230W/m·K, which has still become a "stumbling block" restricting the breakthrough of chip light output. The monocrystalline SiC thermal sink independently developed and produced by Dugen Core in the whole process has brought disruptive heat dissipation solutions to the industry.
