Abstract
The effect of broad-range (10 nm) self-sweeping near 2100 nm in Ho-doped fiber laser has been demonstrated experimentally. The narrowband linearly-polarized tunable radiation with average output power of more than 200 mW is obtained. The use of highly-doped holmium fiber allowed to obtain the widest sweeping range. The polarization maintaining elements and temperature stabilization of the active fiber were applied to stabilize the laser operation. The developed source can be used for spectroscopy of Nitrous oxide, having absorption lines in that spectral region.
