Scientists at the Paul Scherrer Institute PSI have, for the first time, demonstrated a technique that synchronizes ultrashort X-ray pulses at the X-ray free-electron laser SwissFEL. This achievement ...

Because pulse trains achieve excellent performance with a simple laser setup, passively mode-locked fiber lasers (MLFLs) based on nonlinear polarization evolution (NPE) have numerous applications.

Ultrafast laser oscillators are indispensable tools for diverse applications in scientific research and industry. When the phases of the longitudinal laser cavity modes are locked, pulses as short as ...

In a recent review article published in the journal Light: Science & Applications, researchers recently examined advances in ultrafast photonics, highlighting how the combination of nonlinear optical ...

optics.org learns how a simple self-mode-locking design applied to ceramic lasers could aid other high-power lasers. Researchers from Singapore, China and Japan have unveiled what they believe to be ...
