We evaluated the dependence of quantum yield (fluorescent quantum efficiency) of 3at.% Cr:LiSAF on the pump wavelength between 284 nm and 661nn. Because quantum yield of 3at.% Cr:LiSAF was around 0.99, the energy transfer ratio of fluorescence and absorbed pump was approximately equals to the atomic quantum efficiency.
