| 内容記述 | An intense short pulse laser with intensity over 10^21^ W/cm^2^ has become available, i.e. J-KAREN-P at QST. Although the contrast of the short pulse is improved to be of the order of 10^−11^, there is an unavoidable prepulse, which has multiple spikes (~ ps) on top of an exponential profile with intensity greater than 10^14^ W/cm^2^ about 50 ps in front of the main pulse. The prepulse preheats the target and also produces tenuous plasmas in front of a target before the main pulse arrives. It is critical to understand such preheating of the target, where the nonlocal heat transport is essential at intensity >10^14^ W/cm^2^, since the target condition might totally change before the interaction with the main pulse. Using a hydro code, FLASH, and a collisional particle-in-cell code, PICLS, we study the preplasma formation and target preheating over tens of picoseconds timescale, and discuss the prepulse effects on the main pulse interaction. | |||||
