Abstract

The optical absorption spectra of triply ionized neodymium and erbium ions in POCl3∶SnCl4 laser liquid have been studied for the first time in the UV-VIS and NIR regions. Spectroscopic and Judd-Ofelt intensity parameters are evaluated from the observed band positions and their intensities. Radiative lifetimes and the luminescent branching ratios for the excited fluorescent levels of Nd3+ and Er3+ ions are theoretically estimated and the possible laser transitions are indicated. From the observed splittings of certain bands in the second-derivative spectrum of the Nd3+ ion, the crystal field (A20,A40) parameters are evaluated assumingC3h symmetry for the ion.
