Optical Software-Assisted Design and Optimization of Bessel Beam Systems for applications to laser materials processing
Résumé
Bessel beams, known for maintaining focus over long distances, find many applications in imaging, nonlinear
optics and laser material processing. For these applications, generating sub-micrometer Bessel beams is essential,
but requires complex optical systems. Traditional optical software, designed for ray tracing, are challenged for
this task. Here we show how we can use optical software to create and optimize optical design to generate
these unconventional beams. The research involves high numerical aperture systems, investigates the influence
of polarization, and the use of diffractive optical elements. Numerical findings are compared to experimental
results, highlighting the potential of software-assisted beam design for various applications
