Physical systems with co-existence and interplay of processes featuring distinct spatio-temporal scales are found in various research areas ranging from studies of brain activity to astrophysics. The ...

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.

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 ...

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 ...

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 ...
