Popis:	To properly account for nonlinear propagation effects in the design of a large laser system, it is necessary to know the nonlinear refractive index coefficient n2 of each system component. We report values of n2 for YAG, ED‐2 laser glass, EY‐1 Faraday rotator glass, and FR‐4 rotator glass. The measurements were made at 1.06 μm using a time‐resolved Mach‐Zehnder interferometer to directly observe the variation of refractive index with intensity during the transmission of pulses 150 psec in duration.
