Paper Abstract

The measurement of femtosecond pulse laser induced refractive index changes inside transparent solids is challenging since only small phase differences of buried structures on a micrometer scale have to be resolved. Here we report on a new technique that allows to precisely determine the laser-induced refractive index changes in situ. It is based on the modification of an integrated optical Mach-Zehnder interferometer.
