Generation properties of new bichromophore coumarin dyes and the influence on them of the structure changes of a coumarin molecule fragment have been studied. New bichromophores allow generation at lamp and laser pumping in a 585-640 nm spectral range, have high generative efficiency (up to 36%) and a high protochemical stability as compared to the best studied and usable coumarins. The influence of pumping frequency content on generation efficiency of new bichromophores has been investigated.
