Abstract :
Summary form only given. Silicon wafers are mounted inside a vacuum chamber backfilled with gas and then irradiated with 800-nm pulses from a regeneratively amplified Ti:sapphire laser. Following laser treatment, the samples are removed from the chamber and analyzed with a scanning electron microscope (SEM).
