Abstract

We describe lasing of a thulium-doped polarizing photonic crystal fiber. A 4m long fiber with 50 mu m diameter core, 250 mu m diameter cladding, and d/Lambda ratio of 0.18 was pumped with a 793nm diode and produced a polarized output with a polarization extinction ratio ( PER) of 15 dB and an M(2) of < 1.15. An intracavity polarizer and half-wave plate minimally increased the PER to 16 dB. The output power had 35% slope efficiency relative to the absorbed pump power. The maximum cw output power was limited to 4W due to the quantum defect heating of the fiber. (C) 2011 Optical Society of America
