Abstract :
Nonlinear reaction in semiconductors has received much attention recently, partially due to its potential in applications such as optical switching, amplification, and limiting. We report a method to unambiguously determine these three effects, by using the single beam Z-scan technique and single color time-resolved Z-scan technique with a femtosecond laser.
