Paper Abstract

Theoretical considerations of thermal lens effect due to linear and nonlinear optical absorption is presented. Based on this model, Z-scan technique, especially two-color Z-scan due can be used to detect very low level of impurities or defects in optical materials. Depending upon the optical cross section of the particular species being probed, two-color Z-scan can detect impurities, for example, the OH groups in fused silica at sub-ppm level by weight or better.
