We demonstrate for the first time an optically pumped gas laser based on population inversion using a hollow core photonic crystal fiber (HC-PCF). The HC-PCF filled with 12C2H2 gas is pumped with ~5 ns pulses at 1.52 μm and lases at 3.

The observed laser lines correspond to transitions from the terminal pump vibration-rotation state to a combination vibrational state.
