Abstract
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 (λp = 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 (Fig. 1, Fig. 2). The energy variation of transmitted probe beam, which propagates transversely through the plasma self-channeling is measured.
