Gaussian Angle

The Gaussian Angle beam is an optionally decentered TEM(0, 0) mode whose waist size is determined by the far-field divergence half-angle in degrees, measured in air. OpticStudio uses the specified divergence angle to compute the beam waist. The beam waist is given by:

Note that the angle is the half-angle of divergence in degrees, and the wavelength is not scaled by the index of the starting medium. If the x and y angle values are different, then an elliptical beam will be generated. The beam is defined at the waist.
