Paper Abstract

We report on a Tm:fiber master oscillator power amplifier system producing 100 W output power, with >10 dB polarization extinction ratio and diffraction-limited beam quality. To our knowledge, this is the highest polarized output power from an integrated Tm:fiber laser. The oscillator uses polarization maintaining (PM) single mode fiber with 10/130 μm core/cladding diameters, and the amplifier uses large mode area PM fiber with 25/400 μm core/cladding diameters. The oscillator and amplifier are pumped using 793 nm diodes spliced with pump combiners, and the oscillator is spliced to the amplifier via a mode field adaptor.
