MultibeamDefocus models a multibeam pulsed laser source. Each beam has a Gaussian intensity profile with focus applied to the wavefront. The beams are identical, except for their positions in the source plane, and they are mutually incoherent. Each beam has the same specified gaussian beam profile, wavelength, pulse interval, pulse length, focal length, and power per pulse. Each pulse is modeled as being rectangular and symmetric, and ordinarily only a single propagation is performed for each pulse, in the middle of the pulse interval, with a power of pulseEnergy/pulseLength. It has a single WaveTrain output, representing the transmitted light.

Parameters
pulseInterval	double	Interval between pulses (s)
pulseLength	double	Length of pulse (s)
pulseEnergy	float	Power per pulse for each source (J/m^2)
xBeam	Vector<float>	Offsets of Gaussian center in x-direction (m)
yBeam	Vector<float>	Offsets of Gaussian center in y-direction (m)
wavelength	float	Wavelength of sources (m)
sigma	float	Radius of 1-sigma point (m)
defocus	Vector<float>	Focal length added phase of each beam (m)
Inputs
on	bool	Flag for current On/Off state
Outputs
transmitted	WaveTrain	Transmitted multiple pulsed Gaussian beams
