Title

Integrated 100-W Polarized Narrow Linewidth Thulium Fiber Mopa System

Abstract

We describe lasing in polarizing thulium doped PCF fiber for the first time. The ∼4 m long fiber had 50/250 μm core/cladding diameters and hole-diameter to pitch ratio of 0.18. CW lasing was achieved by end pumping with a 793 nm diode in an oscillator configuration. Slope efficiencies of ∼35 % have been obtained with single mode beam quality (M 2 <1.15). The polarization extinction ratio (PER) was >13 dB without any intra-cavity polarizing elements. This fiber, with MFD of ∼36 μm and ∼5.8 dB/m cladding pump absorption, is an attractive option for high energy pulsed amplifiers in the 2 μm wavelength regime. © 2012 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).
