Injection control of the parameters of radiation emitted by a high-power KrF laser pumped by an electron beam

A high-power KrF laser system was developed on the basis of a large-aperture excimer laser with electronbeam pumping and injection control by an electric-discharge master oscillator. The spectral brightness of the radiation of line width ~0.1 cm^-1, tunable near λ = 248 nm, was ~5 x 10¹⁴ W cm^-2 sr^-1 per cm^-1 at a peak power of ~1 GW.
