Design of Laser Beam Delivery Systems beyond Ray Tracing

VirtualLab Fusion software enables the design of lens and mirror systems for laser beam shaping and guidance

Refractive laser beam delivery system for focusing an astigmatic laser diode. The entire system can be simulated and optimized with VirtualLab Fusion.

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

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

The software VirtualLab Fusion enables the 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.

Features of VirtualLab Fusion Software

  • system simulation by combination of ray tracing and fast and accurate physical optics
  • parametric optimization
  • Monte-Carlo tolerancing
  • realistic laser source modeling
  • inverse refractive beam shaper design
  • combination of refractive and diffractive optics
  • easy-to-use positioning concept
Model of a beam delivery system for the focusing of a single mode diode laser beam and the electric field in the focal region

Application Examples

  • BDS.0001: Collimation of Diode Laser Beam by Objective Lens
    In this example VirtualLab’s ray tracing and field tracing simulation engines are applied to investigate the collimation of a beam from a diode laser.

  • BDS.0002: Focus Investigation behind Aspherical Lens
    In this example the collimated light of a diode laser is focused by an aspherical lens and an analysis of the focal region is demonstrated.

  • BDS.0003 Optimization of a Lens Doublet for Laser Beam Focusing
    In this application example a lens doublet is to be designed to focus the beam of a laser diode. This is done by VirtualLab’s parametric optimization tools. Hereby the improvement of a ray tracing design based on field tracing is demonstrated.

  • BDS.0004 Generation of Bessel beam by axicon pair
    In this application example the focal beam size of a laser system with aspherical focusing optics is further reduced by introducing an axicon pair. As a result a Bessel beam-like profile is generated, which has smaller focal beam size than the competitive Gaussian beam.

  • BDS.0005 Collimation of diode laser using an off-axis reflective setup
    The topic of this application example is the realization of a reflective, high-performance, dispersion-free, off-axis optical system, in order to collimate and shape a strong astigmatic Gaussian beam of a laser diode. For this purpose, mirrors exhibiting different shapes are utilized, such as parabolic and cylindrical. After the collimation, the beam quality (M² value) is analysed and an approach for optimization is discussed. Further, the influence of the mirror alignment is investigated, per performing a Monte Carlo tolerancing of the mirror orientations.
