Beam delivery

The design of refractive lens and mirror systems is the basis for laser beam control, including: 

  • collimation  
  • focusing 
  • beam expanders
  • beam guidance 
  • laser scanners
  • transversal beam shaping 

The software VirtualLab Fusion enables further performance improvement of such laser systems obtained from a ray tracing design. This is possible by parametric optimization and Monte-Carlo tolerancing techniques in combination with the unique field tracing simulation engine, which takes physical optics effects (like beam diffraction and polarization) into account.

Evaluation of focus behavior of an astigmatic Gaussian beam behind a focusing asphere.

Ray tracing and physical optics analysis of the focusing of a laser beam by a high-NA asphere, with emphasis on the study of the polarization effects stemming from the extreme non-paraxiality of the system.
