Members

PowerWatts

Total power of the source in units of Watts.

semiAngX

Far field divergence semi-angle (1/e²) in degrees of the source in the X direction.

semiAngY

Far field divergence semi-angle (1/e²) in degrees of the source in the Y direction.

Xnum

Number of samples in the X direction.

Ynum

Number of samples in the Y direction.

Zcreate

Distance (relative to the source waist) at which the beam wavefront is synthesized.  This distance should be larger than the Rayleigh range of the source.

Zseparation

Axial separation (symmetric) of the astigmatic focii.
