Probing Internal Dynamics of Spatiotemporal Optical Vortex Strings: Spatiotemporal Attraction and Filament Stretching

Xiuyu Yao, Xuechen Gao, Ping Zhu, Jintao Fan et autres

ABSTRACT Vortex dynamics are intriguing and challenging across multiple physics fields. In optics, customized spatiotemporally structured optical fields, especially spatiotemporal optical vortices (STOV), offer the potential to tailor light via coupled space‐time degrees of freedom. However, the interaction mechanisms between multiple transverse …

Spatio-spectral characterization of ultrashort-pulse laser with wavelength-scanning ptychography

Qiang Zhang, Xuejie Zhang, Ping Zhu, Xiaomeng Sun et autres

Abstract Spatio-spectral measurement of ultrashort-pulse beam is very important for the performance optimization of laser facilities. A reference-free, spectrally resolved measurement method based on ptychography with an advanced iterative algorithm for high-precision synthesis of full-spectrum data is proposed. We designed an integrated …
