Ultra Short Optics and Laser Resonator Modeling with LightTrans VirtualLab™
With VirtualLab™ 4 LightTrans has released an amazing optics software package, which combines user-friendliness with highly innovative modeling concepts and algorithms.
Each optical component comes with a selection of suitable propagation models, e.g. various geometrical optics versions, Fourier modal method, spectrum of plane waves, split-step method, Collins integral and ABCD technique. All techniques work together on the powerful Unified Optical Modeling platform which ensures an unsurpassed modeling flexibility. The researchers and engineers at LightTrans apply this flexibility to improve the modeling capability of VirtualLab steadily.
At the LASER Exhibition in Munich, 2009, LightTrans presents various new features and products including linear ultra short pulse modeling and laser resonator analysis. Ultra short pulse modeling is implemented in the frequency domain by a Fourier representation of the temporal pulse of any duration. Each harmonic field is propagated through the optical system including lenses and gratings. The modeling includes angular and material dispersion. In any plane of interest the pulse can be reconstructed and inspected at arbitrary lateral positions. All polarization effects are taken into account. VirtualLab™ also provides laser resonator analysis with its new Resonator Toolbox. In its basic version it allows stable cw laser resonator inspection including polarization and micro-optical elements inside the resonator. LASCAD™ users can import their systems for further analysis in VirtualLab™.
