Identifier: http://hdl.handle.net/1959.14/191920
Description: In recent years, the femtosecond laser direct write technique has evolved into a standard technique for the inscription of optical waveguides in glasses. However, due to very slow process speeds and l... More

Identifier: http://hdl.handle.net/1959.14/144480
Description: We report a 790nm pumped, Tm3+ doped ZBLAN glass buried waveguide laser that produces 47mWat 1880nm, with a 50% internal slope efficiency and an M2 of 1.7. The waveguide cladding is defined by two ove... More
