The influence of absorption from excited singlet states (singlet-singlet absorption) on the lasing parameters of ionic (symmetric and asymmetric cationic) and intraionic (merocyanine) polymethine dyes excited by nanosecond 532-nm second-harmonic pulses from a Nd:YAG laser and 308-nm pulses from a XeCl laser is studied. It is shown that singlet-singlet absorption at the pump and lasing wavelengths affects the spectral and energy lasing parameters of organic dye solutions. (lasers)
