激光束整形技术对于优化大量激光材料加工应用和激光材料相互作用研究非常重要。作者开发了一种新型流体激光光束整形器（FLBS），具有灵活性、多功能性和低成本等优点。这项工作提出了一种使用 FLBS 进行激光束整形的全新方法。高斯光束轮廓转换为焦平面中的平顶光束和环形光束轮廓。成形激光束用于激光打孔，以研究激光强度分布对激光加工的影响。本文最后提出了对未来研究和进一步工作的潜在应用的建议。版权所有 © 2013 ASME
Laser beam shaping techniques are important to optimize a large number of laser-material processing applications and laser-material interaction studies. The authors have developed a novel fluidic laser beam shaper (FLBS) with merits such as flexiblility, versatility and low cost. This work presents a fundamentally new approach for laser beam shaping by using FLBS. A Gaussian beam profile is transformed to a flat top beam and annular beam profile in the focal plane. The shaped laser beam is used for laser drilling to investigate the influence of the laser intensity profile in laser processing. The paper concludes with suggestions for future research and potential applications for further the work.Copyright © 2013 by ASME
