Periodical spectral peaking on optical pulses

WebFor optical pulses, timing jitter is related to phase noise in the optical frequency components of the pulse train (see below). In the absence of technical noise, the jitter of a mode-locked laser is limited by quantum … WebFeb 22, 2016 · Due to the use of accurate models, several interesting results are obtained, such as the periodic spatiotemporal evolution behavior, the formation of a stable donut-shaped beam profile, and the increasing of pulse energy during frequency upconversion. It is the use of hollow-core fibers that enables these behaviors to be observed.
