Non relativistic laser intensity

[Khatua03]

Hi all,
As we can see from the EPOCH manual, it is a fully relatistic PIC code. Can anyone suggest that if I use laser intensity way below the relativistic region, how accurate will the results be? Should we work in the relativistic region while using EPOCH?

Thanks.

Hi @Khatua03,

The relativistic equations of motion are still valid for non-relativistic particles, so I think it should be fine.

If you're dealing with a low temperature plasma, you may find you need a greater resolution to prevent self heating. A good test to check your parameters is given in our self heating demo.

Hope this helps,
Stuart

Hi Stuart,
Thank you so much for the reply and suggestion. Yes, you are right about the non-relativistic simulation. I read some papers where they used a 3D epoch for a 1e14 Wcm^-2 power laser.

Thank you.
With best regards,
