Abstract :
The generative characteristics of water and ethanol solutions of dyes were investigated at lamproom and laser pumping. In the experiments the electrodigit excimer laser on XeCl with the energy of generating of 200-300 mJ on λ = 308 nm (the pulse duration of excitation ∼60 ns) and the laser on dyes with pumping by a standard flashlight valve INP-5/75A-1 (energy of pumping - 25 J, pulse duration of pumping on half of intensity - 1 μs) were used. The standard widely known dyes were selected as the object for research: coumarin 1, coumarin120, coumarine 4, rhodamine 110 and rhodamine B. The increase in generating energy of dyes containing a hydroxyl group at the attachment of water to their ethanol solutions is revealed.
