Paper Abstract

This work is concerned with the possibility of getting optical amplification in the uv/visible region by means of doped alkali-halide crystals, pumped by a Nitrogen laser. The Amplified Spontaneous Emission (ASE) technique is adopted with the continuous recording of the luminescence intensity as a function of either the pump intensity or the pumped length. In the latter case the pumping beam inhomogeneity is taken into account. A CsI crystal doped with In+ and T1+ was investigated at room temperature. The fast component of the emission (~10 ns) at 430 nm showed a gain of about 1.5 with a pumping of 104 W/cm on a length of 8mm. There is experimental evidence that the active element is thallium after investigation on CsI:T1+ and CsI:In+ crystals. Negative results of amplification for KI:T1+ and KI:Ag were obtained.
