Title: Generation of a high-quality hollow laser beam by a liquid-core optical fiber
Abstract: A hollow laser beam (HLB) is produced by a liquid-core optical fiber (LCOF) filled with CS <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> . We investigate the dependences of the HLB quality on the laser coherence, the incident angle of the laser beam and the length of the LOCF, obtaining the conditions of high-quality HLBs. The Research results show that the lower laser coherence the better is the quality of HLBs. The quality of HLBs is also influenced by the incident angle of the laser beam and the length of the LCOF. We can achieve high-quality HLBs with longer LCOF when the incident angle of the laser beam is less than 10°. The generated HLBs with high quality can satisfy the needs of different applications.
