Spectral and temporal features of the pumping of rhodamine 6G by radiation from a copper vapor laser

An experimental investigation was made of the influence of the relative delay time τ and of the intensity ratio R₂₁, of the spectral components emitted by a copper vapor laser on the energy and spectral characteristics of lasing in rhodamine 6G. For certain values of τ and P₂₁ lasing in the dye was disrupted. A clamping effect was discovered between the rhodamine 6G laser emission spectrum and the yellow line of the copper vapor laser. The results obtained were used to determine the parameters of an interference filter for suppressing the yellow line from the copper vapor laser, and this made it possible to raise the efficiency of conversion of the pump radiation into lasing in the dye.
