LaserField

MATLAB

Laser = LaserField(x,y,LaserType,TotalPower,lambda,...
                   FocusDistance,[p1,p2,...pN])

Description

Returns structure representing a laser field for use in wave-optics simulation. Structure contains complex grid for laser field consistent with input parameters.

Parameters

Parameters	Description
x [vector]	X centers (vertical axis) for laser field evaluation (m)
y [vector]	Y centers (horizontal axis) for laser field evaluation (m)
LaserType [string]	Identifier for type of laser to model. Supports 'UNIFORM', 'GAUSSIAN', and 'RECTANGULAR' (see comments below)
TotalPower [scalar]	Output power for the laser (W)
lambda [scalar]	Wavelength of the laser (m)
FocusDistance [scalar]	Radius of curvature for beam (m)
p1...pN [list]	Parameter values for laser model options
LaserType	'UNIFORM' 'GAUSSIAN' 'RECTANGULAR'
p1 [scalar]	Diameter of aperture (m). Sigma for irradiance of form $exp(-(r/sigma)^{2})$ (m) Outer side length in x axis (m)
p2 [scalar]	Diameter of central obscuration (m). Diameter of clipping aperture (m). Outer side length in y axis (m)
p3 [scalar]	(Optional) Obscuration side length in x axis (m)
p4 [scalar]	(Optional) Obscuration side length in y axis (m)
