Quasi-optical design and analysis add-on

The QUAST add-on module extends the well-known GRASP analysis methods by Gaussian Beam analysis and accelerated PO, and includes a large number of components to speed up beam waveguide design while maintaining high accuracy, including:

  • Curved mirrors
  • Lenses
  • Beam splitters
  • Polarization grids
  • Aperture stops
  • Rooftop mirrors
  • Interferometers

A special design tool, the frame designer, enables the user to set up planar networks of components and subsequently optimize the components for minimum cross-polarization, maximum confocal distance, specific phase-front radius or phase slippage. 

Several frames can be created and connected to model beam waveguides which are not confined to a single plane. 

Once an attractive design is obtained in the frame, the user quickly generates all the objects necessary for accurate analysis in GRASP through the object wizard. During this process it is possible to determine the reflector and lense curvature to fit the incoming beam; the size of the components can be automatically adjusted to capture a certain amount of the incoming Gaussian beam power.
