Title: Chromium-doped scandium gallium garnet crystals as active media of lasers utilizing Ho/sup 3 +/ and Tm/sup 3 +/ infrared transitions

Abstract

An investigation was made of the luminescence spectra of yttrium scandium gallium garnet crystals activated with Cr/sup 3 +/, Ho/sup 3 +/, and Tm/sup 3 +/ ions. Measurements were made of the excited state lifetime of Ho/sup 3 +/ and Tm/sup 3 +/. Efficient Cr..-->..Ho and Cr..-->..Tm nonradiative energy transfer was observed. The existence of energy transfer mechanisms having a shorter range than the dipole--dipole one was established. The microscopic constants of dipole--dipole interaction were determined. It is concluded that efficient Cr..-->..Ho and Cr..-->..Tm energy transfer suggests that efficient room-temperature lasers may be developed utilizing infrared transitions in these rare-earth ions.
