Shaping self-imaging bottle beams with modified quasi-Bessel beams

Li, Li; Lee, Woei Ming; Xie, Xiangsheng; Krolikowski, Wieslaw; Rode, Andrei V; Zhou, Jianying


Coherent generated self-imaging bottle beams, typically formed by interfering two coherent quasi-Bessel beams, possess a periodic array of intensity maxima and minima along their axial direction. In practice, the overall quality of the self-repeating intensity patterns is prone to unresolved large intensity variations. In this Letter, we increased consistency of intensity of self-imaging bottle beams through a spatial frequency optimization routine. By doing so, we increased the effective...[Show more]
