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 ...

Arguably the best known example of quantum interference was demonstrated by Hong, Ou and Mandel 7 (HOM); their interferometer is depicted in Fig. 1a. HOM interference is central to optical quantum ...

In quantum mechanics, particles such as electrons act like waves and can even interfere with themselves—a striking and counterintuitive feature that defies our classical view of reality. We know this ...

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 ...

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 ...

A new publication from Opto-Electronic Advances, DOI 10.29026/oea.2023.220046 discusses table-top optical parametric chirped pulse amplifiers. The invention of Chirped Pulse Amplification (CPA) ...

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 ...
