Theoretical Temperature-Dependent Branching Ratios and Laser Thresholds of the5I(7)-5I(8) Transition Levels of Ho3(+) in Ten Garnets

摘要

This report presents a comparative study of triply ionized holmium in tengarnets. The point charge model of crystal fields is used to predict the energy levels of Ho3+ in YAG, LaLuGG, GDScAG, YScAG, GdGG, GDScGG, YGG, LuGG, LuAG and GdAG. The magnetic and electric dipole transition probabilities are used to predict theoretical temperature dependent branching ratios and laser thresholds of a quasi four level laser for each of these garnets. Keywords: Branching ratios, Laser threshold, Rare earth, Lasers, Garnets. (js)
