Measurement of Upconversion in Er:YAG via Z-scan

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 0:5-3:0 at:%. A fit to four samples at room temperature yields a value of C(up) = (2.0 +/- 0.5) x 10(exp -17) cu cm/s/at:%. The coefficient at liquid-nitrogen temperatures is C(up) = (9.5 +/- 2.4) x 10(exp -17) cu cm/s/at:%.
