How to add three or more than, laser pulse in EPOCH?

[IBarahimi]

I wrote it as below and ran it but it doesn't work correctly and EPOCH doesn't add three pulse and simulate it but just add one pulse and simulated it

begin:constant
  lambda0 = 1.0 * micron
  temp = 0.0
  dens = 1.0e24 #lab plasma density range
  c_l = 2.99792458e8 #speed of light
  s = -15.0 * lambda0
end:constant

begin:control
  nx = 1500
  ny = 300 #nx
  #npart = 5 * nx * ny
  # final time of simulation
  t_end = 400 * femto
  # size of domain
  x_min = -70.0 * lambda0
  x_max = -x_min
  y_min = -15.0 * lambda0
  y_max = -y_min
end:control

begin:boundaries
  bc_x_min = simple_laser
  bc_x_max = simple_outflow
  bc_y_min = periodic
  bc_y_max = periodic
end:boundaries

begin:laser
  boundary = x_min
  boundary = x_min
  lambda = lambda0
  intensity_w_cm2 = 1.0e18
  #pol_angle = probe_polangle
  profile = gauss(y, 0.0, 5*micro)
  t_profile = gauss(time,14*femto,17*femto)
  t_start = 0 * femto
  t_end = 10 * femto
end:laser
	
begin:laser
  boundary = x_min
  boundary = x_min
  lambda = lambda0
  intensity_w_cm2 = 1.0e20
  #pol_angle = probe_polangle
  profile = gauss(y, 0.0, 5*micro)
  t_profile = gauss(time,14*femto,17*femto)
  t_start = 30 * femto
  t_end = 40 * femto
end:laser

begin:laser
  boundary = x_min
  lambda = lambda0
  intensity_w_cm2 = 1.0e24
  #pol_angle = probe_polangle
  profile = gauss(y, 0.0, 5*micro)
  t_profile = 1
  t_start = 233 * femto
  t_end = 243 * femto
end:laser
			
begin:species
  name = electron
  charge = -1.0
  mass = 1.0
  frac = 1.0
  temp = 0
  density = dens
  npart_per_cell = 5
end:species

begin:species
  #He ions
  name = ions
  charge = 2.0
  mass = 4.0 * 1830
  npart_per_cell = 2
  immobile = T
  density = 0.5e24
  temp = 0.0
end:species

begin:output
  #timesteps between output dumps
  dt_snapshot = 10.0 * femto
  # Properties on grid
  grid = always
  ex = always
  ey = always
  ez = always
  bx = always
  by = always
  bz = always
  #jx = always
  #jy = always
  #jz = always
  #particle properties
  particles = always + species
  #px = always
  #py = always
  number_density = always + species
  #mass_density = always
  charge_density = always + species
  #ekbar = always + species
  temperature = never
end:output

Your 3 pulses seem to be very different in intensity, and there is a uniform plasma in your simulation. I wonder if the noise in the fields is obsuring your lower intensity pulses.

Could you repeat your simulation without any particles present, and show me the outputs you get in the ey field?

I did it.
