Abstract

We demonstrate the use of the z-scan technique for measuring the upconversion coefficient in Er:YAG. The upconversion coefficient is found to be linearly proportional to the concentration for samples of concentration 0.53.0  at.%. A fit to four samples at room temperature yields a value of Cup=(2.0±0.5)×1017cm3/s/at.%. The coefficient at liquid-nitrogen temperatures is Cup=(9.5±2.4)×1017cm3/s/at.%.
