Abstract

Q-switched operation in a thulium doped photonic crystal fiber (PCF) is shown for the first time. The slope efficiencies of 25.9, 31.9 and 33 % were observed for 10, 20 and 50 kHz repetition rates. The high peak powers of >5 kW in the PCF oscillator was used to introduce modulation instability initiated >350 nm broadening in ∼50 m SMF-28 fiber.
