[FLASH-USERS] Modeling Laser Induced Plasma Channel

[Hansen, Eddie]

Hi Victor,

The main problem with modeling short pulses with FLASH, at the moment, is that FLASH’s laser deposition only accounts for absorption via inverse bremsstrahlung. You would need a model for free-bound and bound-bound absorption, which is not in FLASH.

Subject: [FLASH-USERS] Modeling Laser Induced Plasma Channel
Dear all,

I hope you are all well. I have installed and ran FLASH on my university’s HPC. The example that I’m working on is the LaserSlab. I would like to model a 50 fs short pulse propagating through a few cms of a He plasma. The main diagnostic I’m interested in looking at is the plasma density. Would something like this be possible on FLASH? Are there any current example inputs like this? Thank you all.

Best regards,
