Utilization of Rare Earth Ions in Single Crystals in Infrared Quantum Counter-Amplifier Device Application.

Abstract

The report describes laser induced infrared quantum counter (optical double resonance) upconversion experiments. Highly efficient infrared upconversion (at 2.03 micrometers) in LaCl3:Pr(3+), LaF3:Pr(3+), and SrCl2:Pr(3+) has been achieved by means of a tunable cw dye laser pump. The report is given in five parts dealing with the following: crystal growth; infrared upconversion in LaCl3:Pr(3+), LaF3:Pr(3+), SrCl2:Pr(3+); Energy transfer processes between rare earth ions in crystals; and quantum scattering processes in radiationless decay of electronically excited rare earth ions in crystals.
