Abstract :
Summary form only given. The time-resolved dynamics of plasma self-channeling and refractive index bulk modification in the bulk silica glasses were first observed in-situ using a high-intensity femtosecond (110 fs) Ti:sapphire laser laser (/spl lambda//sub p/ = 790 nm). The newly proposed pump-probe measurement was used to study the lifetime of both plasma self-channeling and induced refractive index bulk modification.
