Spectral beam combining of 2 mu m Tm fiber laser systems
Abbreviated Journal Title
AMPLIFIERS; FILTERS; POWER; Optics
Output beams from three independently frequency-stabilized thulium master-oscillator power-amplifier fiber laser systems were spectrally combined using a plane-ruled metal diffraction grating. Two laser channels were frequency-stabilized with guided mode resonance filters and the third was stabilized using a plane-ruled metal diffraction grating. The systems had output wavelengths between 1984 and 2015 nm, each with a spectral width of 100-450 pm and output powers between 40-120W. The combined beam had powers up to 49W and was 32% efficient with respect to the launched pump power. (c) 2011 Elsevier B.V. All rights reserved.
