Abstract

The measurement technique we report here is based on Mach-Zehnder interferemeter with the pump-probe system. By doing so, the classical interference pattern used in Mach-Zehnder interferemeter is modified by a pump beam introducing nonlinearities in the sample. The interference pattern at the output of the setup has been acquired on a C.C.D. camera. In Fig. 1 one can easily see changes introduced in the fringes by the pump beam.
