Afocal Systems for Laser Guide Stars

[July 07, 2020]
We analyze and design such systems in VirtualLab Fusion and show how to configure the Fourier transform settings for such tasks.
[July 07, 2020]

Laser guide stars – which are artificial “star” images tens of kilometers away – are important for the correction of atmospheric distortions for astronomical telescopes. The size of the star must be carefully controlled, and the slow-diffraction effect must be considered in the design so as to correctly predict the focal spot. We analyze and design such systems in VirtualLab Fusion and show how to configure the Fourier transform settings for such tasks.

Beam Clean-Up

[July 01, 2020]
We build up a spatial filtering setup and check how the pinhole size influences the output beam quality and power.
[July 01, 2020]

It is often important to ensure good beam quality for many laser-based optical experiments and applications. Laser beams, in reality, may contain higher-order modes or exhibit wavefront perturbation, and consequently need to be cleaned up. A typical method is to use a spatial filtering setup, with two lenses and a pinhole in the intermediate focal plane, i.e. the Fourier plane. We build up such a spatial filtering setup and check how the pinhole size influences the output beam quality and power.

Modeling Pinhole Diffraction within System

[June 21, 2020]
We demonstrate the modeling of pinhole as well as surface aperture diffraction effects inside a low-Fresnel-number system, and compare the results with the typical exit pupil diffraction approach.
[June 21, 2020]

Diffraction effects are typically considered only at the exit pupil of a system and including intra-system diffraction (especially when it is caused by multiple truncations), as discussed by M. Mout et al., is a challenging task. With the innovations in Fourier transforms, you have direct and flexible control of the diffraction inclusion in VirtualLab Fusion 2020.1. As an example, we demonstrate the modeling of pinhole as well as surface aperture diffraction effects inside a low-Fresnel-number system, and compare the results with the typical exit pupil diffraction approach.

Automatize Your Simulation Tasks

[June 05, 2020]
For the analysis of modern optical devices and systems, engineers often need to execute a large amount of simulations. To assist with such tasks, VirtualLab Fusion provides a flexible inbuilt programming language. It is possible to access VirtualLab Fusion simulations externally, giving you the full possibility to further analyze the simulation results.
[June 05, 2020]

For the analysis of modern optical devices and systems, engineers often need to execute a large amount of simulations to gather and sort the results, so as to fully study the optical design. To assist with such tasks, VirtualLab Fusion provides a flexible inbuilt programming language, which allows, for example, for the automatic saving of the simulation results. Moreover, it is possible to access VirtualLab Fusion simulations externally (via MATLAB or Python), giving you the full possibility to further analyze the simulation results.

Generation of Non-Diffracting Bessel Beams

[May 19, 2020]
We demonstrate how to generate Bessel beams with an axicon, and, following the research work of O. Brzobohatý et al., we investigate how the round tip of the axicon may influence the resulting Bessel beam.
[May 19, 2020]

Nowadays, Bessel-like beams and similar kinds of non-diffracting beams are not just generated in the lab but have been put to use in different applications. To better exploit such beams, their properties must be studied and understood more deeply. As a typical example, we demonstrate how to generate Bessel beams with an axicon, and, following the research work of O. Brzobohatý et al., we investigate how the round tip of the axicon may influence the resulting Bessel beam.
