Bessel Beam Generation

[November 26, 2020]
In the first example, a holographic optical element (HOE) is designed to convert the output of a fiber into Bessel beam directly; the second example investigates the effect from the round-tip of the axicon on the generated Bessel beams.

In the first example, a holographic optical element (HOE) is designed to convert the output of a fiber into Bessel beam directly; the second example investigates the effect from the round-tip of the axicon on the generated Bessel beams.

Bessel beams, because of their unique property of a tight longitudinal focus, are found useful for material processing, optical tweezing, and other applications. In VirtualLab Fusion, we demonstrate the generation of such beams. In the first example, a holographic optical element (HOE) is designed to convert the output of a fiber into a Bessel beam directly; the second example investigates the effect from the round-tip of the axicon on the generated Bessel beams.

Young’s Interference Experiment with Partially Coherent Light

[November 20, 2020]
We investigate in particular the coherence properties of the extended source by checking the change in the contrast of the interference fringes.
[November 20, 2020]

We investigate in particular the coherence properties of the extended source by checking the change in the contrast of the interference fringes.

The double-slit interference experiment was originally conducted by Thomas Young in the early 1800s. It shows the wave-like nature of light and serves as an important technique for spatial coherence measurements. We reproduce Young’s experiment in VirtualLab Fusion, with both a single point source and an extended source. We investigate in particular the coherence properties of the extended source by checking the change in the contrast of the interference fringes.
