Ultrashort mid-infrared (mid-IR) laser pulses are essential for applications such as molecular spectroscopy, nonlinear microscopy, and biomedical imaging, but their generation often relies on complex ...

Ultrafast laser pulses, typically defined by durations in the femtosecond to picosecond range, have revolutionised both fundamental science and applied technology. Their generation and amplification ...

Ultrafast laser pulse characterization is a critical cornerstone in the field of photonics, enabling the precise measurement and reconstruction of optical pulses with durations in the femtosecond ...

Scientists have captured the moment a laser "comes to life"—and what they found challenges long-held beliefs. Using a special technique to film laser light in real time, researchers observed how ...

Scientists have developed a groundbreaking technique called RAVEN that can capture the full complexity of an ultra-intense laser pulse in a single shot—something previously thought nearly impossible.

Scientists working on laser application at the RIKEN Center for Advanced Photonics (RAP) have employed a new technique using GHz bursts of femtosecond laser pulses grouped in MHz envelopes, termed ...

Partnership with Sweden’s Umeå University uses spectral interferometry to sample at different points simultaneously. Improved analysis of an intense laser pulse. The Tata Institute of Fundamental ...

Physicists in Harvard’s John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a compact laser that emits extremely bright, short pulses of light in the “useful” mid-infrared ...
