Abstract

We have demonstrated the laser oscillation of Kr₂* by self-sustained discharge. excitation. This demonstration of the VUV laser oscillation is mainly attributed to the success of the self-sustained glow discharge of high pressure Kr. The maximum output energy at 148 nm was as large as 210 μJ with a pulse width of 250 ns (FWHM). The maximum gain coefficient was 3.5% cm^-1. The discharge pumped VUV Kr₂* excimer laser will open up various application fields where such a compact short wavelength laser is in demand.
