What frequency regime are you interested in?

Daniil Valentinovich Ganin

Sample will be irradiated by 1025 nm femtosecond laser.

According to this: http://opticalengineering.spiedigitallibrary.org/article.aspx?articleid=1157700 the refractive index is between 1.55 and 1.6 for 1025 nm

Yes, is true. But i need nonlinear refractive index-n2. It need to calculation critical power of self-focusing.
