Efficiency of cw HF lasers with resonant optical pumping

M. S. Kurdoglyan, A. N. Oraevsky


Abstract: Numerical studies are made of the amplifying and lasing characteristics of cw HF lasers with resonant optical pumping for various threshold gains g_th and molar concentrations α_HF of HF molecules. It is found that the dependence of the quantum efficiency η_q of these lasers on α_HF is nonmonotonic and the maximum of η_q corresponds to α_HF = 0.002. A comparison is made between the calculated and experimental laser characteristics. A new interpretation is given of the experimentally observed changes in the lasing spectrum with varying α_HF.
