Title

Cw And Pulsed Performance Of Tm-Doped Photonic Crystal Fiber Lasers

Abstract

We demonstrate single-mode, highly polarized output from a thulium-doped photonic crystal fiber (PCF) with 50 μm core diameter and an ultra-large mode area >1000 μm 2. To our knowledge, this is the largest mode area of any flexible PCF and is capable of enabling the generation of high peak powers. In a Q-switched oscillator configuration, this fiber produces peak powers as high as 8.9 kW with 435 μJ, 49 ns pulses, >15 dB polarization extinction ratio and quasi diffraction-limited beam quality. The pulse energy was scaled to >1 mJ in amplifier configuration. © 2012 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).
