Abstract

The dependence of lasing efficiency on pumping wavelength in different dye solution lasers are found and studied for the first time. Doubled frequency of titanium-sapphire laser was used as a tunable pumping source. It is shown that maximal value of lasing efficiency is on a longwave shoulder of an absorption spectrum for all studied compounds. A mathematical modeling study was used in order to state the mechanism of lasing efficiency spectra forming. It was shown that these spectra are not due to singlet-singlet or triplet-triplet transient absorption. Such a behavior takes place at high solution concentrations, pumping densities and quality of a cavity.
