Presentation at Laser Optics Berlin

(March 01, 2010)

The modeling of fs pulses is one of the latest achievements of the research and development team at LightTrans. One of the algorithmic innovations is the quasi-analytical treatment of material dispersion that keeps the sampling effort in  the frequency domain small enough.Frank Wyrowski (Univer...

VirtualLab™ 4.6 Released

(January 31, 2010)

LightTrans is pleased to announce the release of VirtualLab™ 4.6!

VirtualLab™ and VirtualLab™ Advanced 4.6 have been released. Version 4.6 enables the rigorous electromagnetic analysis of 3-D index-modulated gratings. The index-modulation can be described by a pillar-type medium that can be used to...

Design of Diffractive Beam Splitters, Diffusers, and Beam Shapers

The VirtualLab™ Diffractive Optics Toolbox allows you to design diffractive beam splitters, diffusers and beam shapers. These elements are also known as diffractive optical element, computer generated hologram, phase plate or kinoform. Diffractive beam splitters allows you to split a laser beam into beam arrays or beams with arbitrary angles of deflection. Not only can you individually determine the weight of every split beam, but you can also design additional diffractive diffusers to generate circular, rectangular or arbitrary 2-D output patterns. This Toolbox allows you to optimize your diffusers for coherent and partially coherent light sources in order to develop homogenizing or pattern-generating systems for LEDs and excimer lasers. Diffractive and refractive beam shapers enable the reshaping of the intensity profile of coherent laser beams into circular, rectangular Top Hats or 2-D intensity patterns. In difference to diffusers generated intensity distributions will be free of speckles and will have high homogeneity and  high efficiency. Diffusers, beam splitters and beam shapers can be designed for paraxial and non-paraxial setups.


The VirtualLab™ Diffractive Optics Toolbox contains powerful tools for design of diffractive diffusers, beam splitters and beam shapers.
