Ultrafast lasers articles from across Nature Portfolio

Here the authors propose a mechanism for direct space-time manipulation of ultrafast light field and experimentally demonstrate the generation of a spatiotemporally coupling light spring with a broad topological charge bandwidth.

The WavemiX network has made significant progress in bringing together theoreticians, experimentalists, and machine scientists. At the third edition of its flagship workshop, different communities collaborated to discuss the practical challenges of achieving superior spatial and time resolution and devise useful applications in ultrafast science.

Prof. Peter Delfyett has been working on semiconductor mode-locked lasers and optical frequency combs, and his research has sped up the transmission of information.

Coherent multi-octave mid-infrared waveforms are created and manipulated by cascaded intrapulse difference-frequency generation, demonstrating absolute phase control, and adding to the growing arsenal of techniques for arbitrary light-wave control.

Four-wave mixing near atomic resonances offers new opportunities for spectral control of extreme ultraviolet pulses.

New methods to control how laser pulses propagate inside a plasma could signify the start of a global race to demonstrate truly high-energy compact particle accelerators.
