Abstract:
Laser oscillation at 2054 cm(-1) has been observed from a vibrational transition of the CN(-) molecule doped into KBr host crystals. At sufficiently large CN(-) concentrations, population inversion between the nu = 2 and nu= 1 vibrational levels is created by optical pumping of the 0 ? 1 transition followed by an efficient vibrational-energy exchange process.
