Setting up two lasers separated in space

[DanRRRR]

How to setup two lasers separated in space by some distance ? It looks like the lasers axis always go on the boundary through the point of y=0, z=0

[TomGoffrey]

This ought to be straightforward. Could you post the input deck that you have tried using please?

Dear Tom,
Thanks for respond.
Here is simplest demo.
How to land not one but two lasers on the left and right of this target ?

begin:control

  nx    = 600
  ny    = 600

  nprocx = 1

  x_min =   0
  x_max =  30. * micron
  y_min = -15. * micron
  y_max =  15. * micron

  t_end = 200 * femto
  stdout_frequency = 100
end:control

begin:constant
  lambda0  = 2.* micron
  omega    = 2 * pi * c / lambda0


  t_fwhm  = 15 * femto
  y_fwhm  = 3. * micron
  wt = t_fwhm /sqrt(2*loge(2.))
  wy = y_fwhm /sqrt(2*loge(2.))

  th = 5 * micron
  xi = x_max / 2.
  xo = x_max / 2. + th

  den_H = 1.e26

#  Hcharge = 1
  r = sqrt(y^2 + z^2)

end:constant

begin:boundaries
  bc_x_min = simple_laser
  bc_x_max = open
  bc_y_min = open
  bc_y_max = open
end:boundaries

begin:species
  name = proton
  charge = 1
  mass = 1836.2
  number_density = if((x gt xi) and (x lt xo), den_H, 0.0)
  npart_per_cell = 3
end:species

begin:species
  name = electron
  charge = -1.0
  mass = 1.0
  number_density = number_density(proton)
  npart_per_cell = 3
end:species

begin:laser
  boundary = x_min
  intensity_w_cm2 = 1.e20
  lambda = lambda0
  t_profile = gauss ( time , 50. * femto, wt )
  profile = gauss (y, 0., wy )
  pol = 0.
end:laser


begin:output
  name = normal
  file_prefix = g
  dt_snapshot = 10 * femto

  grid = always
  ex   = always + single
  ey   = always + single
  ez   = always + single
  bx   = always + single
  by   = always + single
  bz   = always + single

#  number_density = always + average
end:output

Thanks. What's the plot you've attached? There's no labels?

[DanRRRR]

Shown are the E field and flat hydrogen target energy of some density. The parameters do not matter, what not clear is how to shift the laser left and right. I can add second laser but it will be hitting exactly the same place in the center

Here is what's needed

[TomGoffrey]

You ought to be able to modify the line profile = gauss (y, 0., wy ) with something like profile = gauss (y, y0, wy ), where y0 is the center of each laser pulse. See the documentation: https://epochpic.github.io/quickstart/basic_examples/laser.html#laser-pulse

[DanRRRR]

Thanks Tom, Indeed it is so simple that I have no explanation why I even asked, excess heat is the reason probably

[DanRRRR]

The problem I also got here is that if intensity is set as

intensity_w_cm2 = 1.E20

The parser gets an error that it does not understand E20. The e20 it understands, but this is very unusual.
Do you see the same error?
