Single-frequency laser operation near 2 μ m has been demonstrated in an all-fiber short-cavity ( 2 6 cm ) distributed feedback laser cavity using both cladding- and core-pump configurations in a newly developed heavily Tm-doped multicomponent silicate glass fiber. Using a single-mode Er-doped fiber laser at 1575 nm as a core-pump source, a 2 - cm -long distributed Bragg reflector fiber laser delivers single-frequency output at 1950 nm with laser linewidth less than 3 kHz , which is, to the best of our knowledge, the narrowest linewidth demonstrated to date from any 2 μ m single-frequency laser.
