Quantum efficiency measurements of Nd:YAG, Yb:YAG, and Tm:YAG

Quantum efficiencies of Nd: YAG, Yb: YAG, and Tm: YAG were measured using several different approaches. Good agreement is obtained for Nd: YAG and Yb: YAG utilizing 2 different approaches. Because of high fluorescence absorption, Tm: YAG measurements required a different method.
