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 ...

Femtosecond laser pulses, with durations on the order of 10⁻¹⁵ seconds, have transformed the landscape of ultrafast optics by enabling the exploration of rapid light–matter interactions. The dynamics ...

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 ...

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 ...
