Blue laser action by the rare-gas halide trimer Kr2F

Abstract

Blue Kr2F excimer laser emission centered at 430 nm has been achieved in electron-beam-pumped high-density Ar/Kr/Nf3 mixtures. An output power of about 5 kW has been obtained. The spectral bandwidth is 25 nm for a simple two-mirror resonator with a potential tuning range between 380 and 480 nm.
