ABSTRACT

Wavelength and power characteristics of impact periodic two-stage laser composed of exciter and multipass amplifier are investigated. The conditions for suppressing broadband background and increasing of the power transformation efficiency into a narrow injected line are defined. The obtained experimental results match well with theoretical findings. It is developed a high-power narrowband tunable impact-periodic dye laser with lamp pumping providing for average oscillation power of more than 4 W at the line width of 0.1 nm and overlapping the spectral range 460 to 680 nm.
