Abstract
Numerical calculations on the formation of spectral-energy characteristics of the radiation from multipass amplifiers (MPA) of fleshlamp-pumped dye lasers are carried out. Analysis of experimental results has shown that at the MPA output, besides the amplified monochromatic radiation, one can observe a broadband radiation with the energy    depending on the injected signal power. The calculated minimum level of the injected power providing the background radiation elimination within the limits of a sufficiently broad tuning band in the system
(AX – 17 nm) was of about 10 kW that coincides with the known experimental results.

KEY WORDS:  multipass amplifier, dye laser, energy, lasing spectrum
