Ho-doped fiber laser with wavelength self-sweeping near 2.06 μm for CO2 spectroscopy

We report the first results on wavelength self-sweeping operation of a Holmium-doped fiber laser near 2.06 μm with sweeping range of ~ 4 nm and sweeping rate of ~4 nm/sec. The developed source is suitable for spectroscopy of carbon dioxide in contrast to previously designed self-sweeping lasers operating near 2 μm spectral range.
