Abstract

Electronic plasma induced by a focused femtosecond pulse (130 fs, 800 nm) in fused silica was investigated by use of pump–probe technology. Pump and probe shadow imaging and interferometric fringe imaging were combined to determine electronic collision time τ in the conduction band, and τ was measured to be 1.7 fs at an electron density near 5×1019 cm-3. The lifetime of the electronic plasma is also measured to be 170 fs by use of the time-resolved shadow imaging technique.
