Researchers demonstrate highly chirped pulses created by a using a spectral filter in a Kerr resonator, enabling them to widen a laser pulse wavefront by separating the beam's colors. The chirped ...

Physicists in Sweden have come up with a new way of accelerating ions using intense laser pulses. The technique – which has not yet been tested in the lab – involves bouncing “chirped” pulses from a ...

Researchers led by Prof. Tianye Huang at China University of Geosciences (Wuhan), China, are interested in the passive Kerr-resonators-based dissipative cavity solitons. The pulsed driving is an ...

A physics professor is proposing to use femtosecond, chirped laser pulse trains to reduce decoherence. Controlling coherence can overcome current barriers in a variety of fields, from quantum ...

The 2018 Nobel Prize in Physics was shared by researchers who pioneered a technique to create ultrashort, yet extremely high-energy laser pulses at the University of Rochester. Now researchers at the ...

Using laser pulses of a few tens of femtoseconds, chemists can study the motion of atoms during chemical reactions and biologists can witness the earliest steps in natural processes, such as ...

Mentor: Burcin Bayram, Ph.D. A chirped pulse is a short optical or electromagnetic pulse in which the frequency and phase change over time. The use of chirped laser pulses, where the laser frequency ...

A pulse in which the wavelength changes during the duration of the pulse. In a diode laser, chirp arises from direct modulation of the laser, because the refractive index changes with the electron ...

A photonic crystal fibre has for the first time been engineered to transmit sub-100 fs pulses over extended distances. Researchers from Russia and Germany have fabricated a chirped photonic crystal ...
