CW hollow-core optically pumped I2 fiber gas laser.

Continuous wave lasing of a hollow-core fiber gas laser (HOFGLAS) is achieved with molecular iodine in the 1280-1340 nm region when optically pumped at 532 nm.

Molecular C2H2 and HCN lasers pumped by an optical parametric oscillator in the 1.5-microm band.

Lasing of HCN and C(2)H(2) in the 3-micron region was demonstrated with a ns pump emitting in the telecommunication C band (1.5 micron region). The observed laser lines correspond to transitions from the terminal pump vibration-rotation state to a combination vibrational state.
