High-power cladding pumped Tm-doped silica fiber laser with wavelength tuning from 1860 to 2090 nm

A high-power double-clad Tm-doped silica fiber laser, pumped by two beam-shaped and polarization-coupled diode bars at 787nm, was wavelength tuned by use of an external cavity containing a diffraction grating. The Tm fiber laser produced a maximum output power of 7W at 1940nm for 40W of incident dio...

Description
Summary:A high-power double-clad Tm-doped silica fiber laser, pumped by two beam-shaped and polarization-coupled diode bars at 787nm, was wavelength tuned by use of an external cavity containing a diffraction grating. The Tm fiber laser produced a maximum output power of 7W at 1940nm for 40W of incident diode power and was tuned over a wavelength range of 230nm from 1860 to 2090nm, with 5 W output power over the range 1870 2040nm. The prospects for further improvement in performance and extension of the tuning range are discussed.
