Abstract
It is proposed to generate broadband radiation by stimulated Raman sca ttering from rotational levels of atmospheric nitrogen under the condi tions of a strong parametric coupling when the pump radiation is provi ded by a high-power two-frequency neodymium laser. Various systems for constructing such a two-frequency laser are proposed. It is shown tha t up to 20 Raman components can be generated if the intensities of the lines, separated by the 76 cm-1 frequency of the S0(8) transition in nitrogen, is 2 GW cm-2 and the length of the air path is 20 m.
