Abstract
We present time-resolved measurements of the electronic and the nuclea r contributions to the third-order nonlinearities of Ti:sapphire and C r:LiSGaF. The results suggest that nonlinear refraction in Ti:sapphire is resonantly enhanced relative to that of undoped sapphire. The impl ications of the nonlinear responses for short-pulse formation are disc ussed. (C) 1998 Optical Society of America.
