Catching the Ultrafast Motion of Plasma – AS it occurs, WHERE it occurs

Ultrashort (femtosecond), ultra-intense (>10^18 W/cm^2) laser pulses impinging on a solid can produce hot and dense plasma. Its rapid, turbulent evolution poses many difficulties in its measurement. We have recently developed 2-D techniques to see the ‘face’ of such a plasma as it moves, brightens, and dims in a cyclical fashion. In this talk, we will see the challenges faced and the innovations made to catch these events on femtosecond timescales simultaneous with micron spatial scales.
