[FLASH-USERS] Simulation of 30fs laser-foil interaction

[Shu Zhang]

Hi Shizheng, 

You can use PIC code to simulate this short time scale. The magnetic field can be generated by the current of fast electrons escaping from the target, which is not considered in FLASH.

And I am not sure weather Flash4.6.2 can simulation the fs laser interact with matter.
