Time-Resolved Observation of Ultrahigh Intensity Laser-Produced Electron Jets Propagating through Transparent Solid Targets

We report on shadowgraphic measurements showing the first space- and time-resolved snapshots of ultraintense laser pulse-generated fast electrons propagating through a solid target. A remarkable result is the formation of highly collimated jets (<20-μm) traveling at the velocity of light and...

Yhteenveto:We report on shadowgraphic measurements showing the first space- and time-resolved snapshots of ultraintense laser pulse-generated fast electrons propagating through a solid target. A remarkable result is the formation of highly collimated jets (<20-μm) traveling at the velocity of light and extending up to I mm. This feature clearly indicates a magnetically assisted regime of electron transport, of critical interest for the last ignitor scheme. Along with these jets, we detect a slower (≈c/2) and broader (up to 1 mm) ionization front consistent with collisional hot electron energy transport.
