Beam quality factor, spot rotation angle, and angular speed in general laser beams
Zhen-Xiang Hao, Ruo-Xi Wu, Hong-Bo Jin +2
A unified definition for the rotation angle and rotation angular speed of general beams, including those with orbital angular momentum (OAM), has been lacking until now. The rotati…

Approximate model for the coupling of far-field wavefront errors and jitter in space-based gravitational wave laser interferometry
Ya-Zheng Tao, Rui-Hong Gao, Hong-Bo Jin +3
Space-based gravitational wave observatories, such as LISA, Taiji, and TianQin, employ long-baseline laser interferometry, necessitating displacement measurement sensitivity at 1 p…

Method comparison for simulating non-Gaussian Beams and Diffraction for Precision Interferometry
Mengyuan Zhao, Yazheng Tao, Kevin Weber +4
In the context of simulating precision laser interferometers, we compare via several examples two wavefront decomposition methods: the Mode Expansion Method (MEM) and the Gaussian…
