2025-06-23 Processing results on the surfaces of aluminum sheets using picosecond laser beams delivered over free space, 3-m-long AR-HCF1 and 3-m-long AR-HCF2 doi:10.57760/sciencedb.26609 en We demonstrated the high-quality delivery of high-power, picosecond laser pulses over a 3-m-long AR-HCF sample for laser micromachining applications. The experiment results show that the AR-HCF sample with a d/D value of ~0.68 exhibits high optical mode purity, which is critical for overcoming the laser beam instability due to fiber micro-bending. Single-shot and in-line processing procedures of aluminum sheets were performed in our experiments, verifying that the ultrafast laser beam delivered through 3-m-long AR-HCF sample can be used to achieve similar manufacturing quality with that delivered over free space. anti-resonant hollow-core fiber; laser micromachining; mode purity 常新硕 蒋奇男 黄志远 潘劲宇 刘冬涵 张庆伟 李楠 罗卓昭 殷若琛 何文彬 黄家鹏 冷雨欣 江昕 杨上陆 庞盟 PUBLIC https://creativecommons.org/licenses/by-nc-nd/4.0/ dataset Science Data Bank
