We report a 790 nm pumped, Tm³⁺ doped ZBLAN glass buried waveguide laser that produces 47 mW at 1880 nm, with a 50% internal slope efficiency and an M² of 1.7. The waveguide cladding is defined by two overlapping rings created by femtosecond direct-writing of the glass, which results in the formation of a tubular depressed-index-cladding structure, and the laser resonator is defined by external dielectric mirrors. This is, to the best of our knowledge, the most efficient laser created in a glass host via femtosecond waveguide writing.
我们报道了一种 790nm 泵浦的掺 Tm³⁺ ZBLAN 玻璃埋波导激光器，它在 1880nm 处产生 47mW 的功率，内部斜率效率为 50%，M²为 1.7。波导包层由两个通过飞秒直接写入玻璃形成的重叠环定义，这导致形成了管状的折射率降低包层结构，而激光谐振腔由外部介电反射镜定义。据我们所知，这是通过飞秒波导写入在玻璃基质中产生的效率最高的激光。
