Abstract :
Spectral-luminescent and lasing properties of new derivatives of Coumarin-7 were studied. Induced emission generation of studied dyes was observed in the red wave-length region of spectrum. The efficiency of lasing was equal to 40%. The threshold of generation of dyes was observed upon excitation with the power density less than 0.01 MW/cm2. It was revealed that studied dyes have a high photostability.
