[FLASH-USERS] Need help on Simulating fs Laser Interaction in FLASH

[Laxman Goswami]

Dear Users,

I am new to using FLASH simulations. Recently, I attempted to simulate the
interaction of a femtosecond (fs) laser pulse with a helium (He) target.
However, I observed very little absorption of laser energy (approximately
0.008%).

>From my research, I found some suggestions indicating that FLASH may not be
suitable for studying fs laser interactions, as it primarily accounts for
Bremsstrahlung ionization.

Could you please advise me on the correct approach to perform these
simulations? Am I missing something in my setup, or is FLASH inherently
limited for this type of problem?

I would greatly appreciate any guidance or suggestions.

Thank you for your time and help.

Best regards,
Laxman
