HIGH ENERGY CRYSTALLINE LASER MATERIALS

Abstract

The spectroscopic study of GdA103 doped with Cr3+ between 2 and 300 K revealed a structure to the 'R' lines which is described by a ferro-magnetic exchange interaction with the Gd3+ ions, with J = 2.1 reciprocal centimeters for the ground state and J = 3.2 reciprocal centimeters for the excited state of Cr3+. The selection rules on the transitions are qualitatively discussed in order to explain the change in the fluorescence spectrum between 2 and 4 K. The fluorescence lifetime is 9.0, 15.4, and 18.0 ms at 2.0, 4.2, and 77 K respectively.
