Issue with Custom Laser Profile and propagation about fbpic HOT 3 CLOSED

This issue is resolved, Thanks to @RemiLehe for suggestion.

Thanks for raising this issue.

My impression is that the problem comes from this line:

        profile = np.exp(exp_argument)*np.sin((np.pi*(prop_dir *(z - self.z0) - c * t))/(c*tau)) / stretch_factor ** 0.5

From this line, it seems that you would like the envelope of the laser to be a sinusoidal function np.sin. However, you are then getting multiple lasers because np.sin is a periodic function. I think that you should in addition use np.where to set the envelope to 0 unless z is close enough to z0.

Thanks for suggestions Sir, I am trying to achieve that, will update once its done. and will let you know how its done
