Abstract High-power stimulated radiation was obtained in three fluorides of rare gases by exciting a high pressure mixture of He+R+SF6 (R is argon, krypton, xenon) by a pulse electric discharge (mixture pressure ranged from 1 to 10 atm). The ArF laser superradiance spectrum of about 15 Å total width with the centre at λ=1932 Å is given. The ArF laser power wasP≈104 W. The KrF laser generated 2 ns pulses of about 2.5 MW power at λ=2486 Å with a linewidth Δλ≈10 Å. This laser efficiency in relation to the stored energy of an accumulator is about 0.2%. In the XeF laserP=200 to 300 kW, τ=3 to 3.5 ns, λ=3511, 3531 Å. High density of superradiance power is observed. The prospects of increase of mean power of excimer lasers are discussed.
