Abstract

The vibrational properties of the laser-active Tl°(1) center in KCl have been studied by means of resonant Raman scattering. This center consists of a substitutional Tl° atom with a negative ion vacancy in a nearest neighbor position and possesses C_4v[001] symmetry.¹ It was found to be an attractive laser-active center with output in the infrared around 1.5 μm upon optical excitation of the 1.05 μm optical absorption band.²
