Beams

abstract type AbstractBeam{T}

Serves as abstract type for GeometricBeam and GaussianBeam.

GeometricBeam(w=0.0, k=0.0, z=0.0)

Defines a geometrical ray beam with keywords. Distance to the axis is w, the angle with respect to the axis is k. zpos is the initial position along the optical axis.

See also GaussianBeam.

z(beam::GaussianBeam)

Return the distance to the beam waist z of the Gaussian beam.

See also z,zR,w,R,w0.

z(beam::GaussianBeam)

Return Rayleigh length zR of the Gaussian beam.

See also z, w, R, w0.

R(beam::GaussianBeam)

Return curvature R of the Gaussian beam.

See also z, zR, w, w0.

w0(beam::GaussianBeam)

Return w0 of the Gaussian beam.

See also z, zR, w, R.

w(beam::GaussianBeam)

Return current width w of the Gaussian beam.
