Abstract
- We describe and demonstrate a novel experimental technique to record two picosecond-separated images of the evolution of a single-shot laser-produced plasma using a two-color probe beam. In this technique, the probe beam was first partially frequency doubled. The 1 ω and 2 ω components were then temporally separated in a dispersive medium. The pulses remained intrinsically synchronized, both having a duration of ∼150 fs, but they were separated by 4.1 ps. Using a Nomarskii-type interferometer, this novel technique was used to obtain two time-resolved snapshots of the evolution of the electron density at different time steps during the formation of a relativistic plasma channel.
