Spectral and generation properties of a new laser crystal (Cr3+,Li) : Mg2SiO4

Based on the results of a comparative analysis of luminescence spectroscopy and EPR spectroscopy data, it was found for the first time that the wide-band luminescence of Cr3+ ions in a forsterite crystal is due to the Cr3+-V-Mg center or, in a crystal additionally doped with lithium, to a Cr3+-Li+ center. For the first time, tunable laser action was obtained with Cr3+-Li+ centers responsible for the wide-band luminescence. (c) 2005 Pleiades Publishing, Inc.
