WebIn optical fibers with anomalous chromatic dispersion, the chirp from self-phase modulation may be compensated by dispersion; this can lead to the formation of solitons . In the case of fundamental solitons in a lossless fiber, the spectral width of the pulses stays constant during propagation, despite the SPM effect. WebFeb 7, 2024 · By introducing a linear chirp into a ring Airyprime beam array, an optimization scheme to simultaneously achieve the enhancement of autofocusing ability and the extension of focal length is proposed.

WebRemarkable nonlinear chirp was observed in the experiments when Kerr media compared with that measured by NOPA. The results indicate that the chirping introduced by Kerr media is significant and cannot be neglected, especially when the Kerr gate is employed in broadband femtosecond time-resolved ultraviolet-visible spectrum measurements.
