Abstract

We report a novel, Tm-doped photonic crystal fiber (PCF) actively Q -switched oscillator that provides 8.9 kW peak power with 435 µJ, 49 ns pulses at 10 kHz repetition rate at 2 μm wavelength. This fiber has a mode-field area > 1000 μm 2 , the largest of any flexible PCF providing diffraction-limited beam quality to the best of our knowledge. As an application, the oscillator is used as pump to generate > 350 nm broadening in 50 m of SMF-28 fiber.
