Abstract :
This work studies the laser spectrum peculiarities of the benzopyrane dye which have high quantum yield of fluorescence (q ≥0.96) and high-performance lasing under laser pumping as well as flashlamp one. This dye - LD1 differs in that its lasing spectrum consists of two bands in nonselective cavity under laser pumping. Shift distance between the centers of these bands exceeds the full width of them more than twice.
