Laser technology confines light inside a resonator containing a gain medium, a material with quantum properties that can amplify light. As laser resonators are generally far larger than the wavelength ...
Mode-locked fibre lasers, featuring ultrafast temporal information, ultrahigh peak energy, and exceptional stability, have become essential tools in modern optics and industries, including ...
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.

EPFL’s chip-scale laser fires femtosecond pulses on par with bench instruments that fill a whole table, a shrink that could push ultrafast optics into everyday devices
A team led by EPFL has built a laser on a single photonic chip that fires femtosecond pulses with energy and speed that, until now, required bench-top instruments occupying an entire optical table.
Mode-locked lasers are imperative for the generation and application of coherent optical frequency combs. Low noise is necessary for many applications. However, the current super low noise MLLs are ...
IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. This object was made under direction ...
Raman spectroscopy is a non-destructive analytical method that generates complex information about the phase, chemical structure and crystallinity of sample matter. A range of molecular interactions ...
Plasmonic metasurfaces are artificial 2-D sheets of plasmonic unit cells repeated in a subwavelength array, which give rise to unexpected wave properties that do not exist in nature. In the linear ...
