Molecular C_2H_2 and HCN lasers pumped by an optical parametric oscillator in the 15-μm band

Abstract

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.
