$Design of Diffractive Beam Splitters and Diffusers - LightTrans ...$

Modeling Physical States in Optical Cavities Applications The VirtualLab Laser Resonator Toolbox is designed to solve your resonator modeling tasks. For LASCAD users it offers extended techniques for analyzing laser resonators using Fox- Li and Arnoldi algorithms. In a typical application scenario, you are asked to specify your laser resonator configuration by selecting components, such as mirrors, interface sequences, index-modulated media, laser crystal, diffractive optical ele- Tools The Laser Resonator Session Editor assists you in configuring your resonator and preparing your analysis. The Editor supports LASCAD resonator data. In the Toolbox, the resonator analysis of resonator eigenm Sequences of aspherical and spherical interfaces are combined in the AIS component. The propagation through the AIS is modeled by geometrical optics or a combined geometrical-physical optics technique. ments, ideal components like the ideal lens or a generalized Jones matrix. You then begin the eigenmode analysis to obtain the fundamental mode and its eigenvalue. All parameters of this mode can be detected, including the beam waist and M² value. Polarization effects can be included, as well as the bandwidth of transition levels. is stored and displayed in the Light Path View and an Editor where you can modify the parameters. Moreover, you may add other components which are not supported by LASCAD. In VirtualLab the resonator is configured in the light path diagram flow chart. The Laser Resonator Session Editor assists you with importing the resonator data from LASCAD.
odes, M² and other beam parameters Components 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. Detectors The modes are displayed in the Light View, in which you can access the amplitude, phase, and polarization at a mouse click. The Beam Parameter Detector can be used to calculate all relevant mode parameters. Eigenmode Analyzer The Eigenmode Analyzer controls the Fox-Li or Arnoldi eigenmode calculation. It also monitors the convergence of the techniques. It provides you with the resulting fundamental and higher modes, as well as the eigenvalues. Moreover, it estimates the output power of the resonator. Application with other Toolboxes In combination with the Starter Toolbox, you can use the calculated modes as a source in your system modeling which allows you to analyze the mode propagation outside of the cavity. Moreover, you can employ the Eigenmode Analyzer for any optical system. The Diffractive Optics Toolbox and the Beam Shaper Toolbox enable the design of beam splitters, diffusers and beam shapers for application inside the resonator. The Grating Toolbox provides you with any type of grating for internal use.
