AI Article Synopsis
- Researchers have successfully created a spatiotemporal optical vortex (STOV) that features transverse orbital angular momentum (OAM) from coherent ultrafast pulses using mode-locked lasers.
- The study shows that STOVs can also be generated from light sources that have partial temporal coherence and varying temporal patterns.
- This development offers a more convenient and cost-effective alternative for producing transverse OAM sources, as it removes the reliance on expensive mode-locked lasers.
Article Abstract
Recently, a spatiotemporal optical vortex (STOV) with a transverse orbital angular momentum (OAM) has been generated from coherent ultrafast pulses using mode-locked lasers. In contrast, we demonstrate theoretically and experimentally that a STOV can be generated from a light source with partial temporal coherence with fluctuating temporal structures. By eliminating the need of mode-locked laser sources, the partially coherent STOV will serve as a convenient and cost-effective transverse OAM source.
