Components of Laser Resonator Toolbox
The Laser Resonator Toolbox comes with a wide variety of ideal and real components. The ideal ones act in one plane and manipulate the field. Manipulations include ideal lenses and mirrors, apertures and stops, a phase retarder, polarizer and generalized Jones matrices to model thermal polarization effects, for example. Real components include real lenses and mirrors, general aspherical interface sequences, index-modulated regions including GRIN lenses, diffractive optical elements, and, of course, the laser crystal imported from LASCAD. The eigenmode analysis requires simulation of the round-trip operator. To this end, each component comes with suitable propagation techniques, such as the split-step method, free-space propagation, and geometrical optics.

- Sequences of aspherical and spherical interfaces are combined in the AIS component. The propagation through the AIS is modeled by pure geometrical optics (GeOp Operator) or by a sequence of geometrical optics and free-space propagation (GOFS Operator). This sequence is identified and optimized automatically.
