Chirp measurements in radar applications are used to determine the quality of transmitted pulses. The primary quality indicators revolve around the need for the transmitted pulse to be free of ...

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 ...

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 ...

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 ...

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 ...

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 ...

With omnidirectional and sector-scan sonar systems seeing a significant increase in use, especially in ­tournament fishing, it is important to note that this is not an option for everyone. Cost, ...

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 ...

Canadian scientist, Professor Donna Strickland, has been named joint winner of this year’s Nobel Prize for Physics. It is the first time in 55 years (and only the third time ever) a woman has won the ...

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 ...
