FIG. 2.

Measured transient transmission changes as a function of time delay for central wavelengths of (from top to bottom) 356, 362.6, 363.6, and 366 nm with a photoexcited carrier density of . All traces are in the perturbative regime. Traces are vertically displaced for clarity. Dotted lines are convolution fits. The pulse autocorrelation function is shown in dashed line.
