Researchers have developed an innovative and versatile system designed for a new generation of short-pulse lasers. Lasers ...

Researchers in Quebec, Canda, have developed the first fiber laser that can produce femtosecond pulses in the visible range of the electromagnetic spectrum. Fiber lasers producing ultrashort, bright ...

Conceptual depictions of wavenumber-selective nonlinear wavelength conversion in Kerr photonic crystal microresonators. Spatial modulation of the microresonator inner sidewall (pictured center) with a ...

Lasers that emit extremely short light pulses are highly precise and are used in manufacturing, medical applications, and ...

A team at the University of Stuttgart has engineered a compact short-pulse laser that achieves up to 80% efficiency—far ...

Years of research and development work have made compact, high-performance lasers ubiquitous for the near-infrared wavelengths used in telecommunications. However, lasers with an output in the visible ...

Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening new possibilities for technologies that could use a laser beam to control ...

Laser cutting techniques are usually powered by high energy beams, so hot that they melt most materials. Now scientists from McGill University, Montreal, Canada, have developed what they are calling ...
