摘要

报告了三种最常用的商用聚合物（聚氯乙烯 (PVC)、聚对苯二甲酸乙二醇酯 (PET) 和聚丙烯 (PP)）在高重复频率 (1 kHz-1 MHz) 飞秒 (450 fs) 多脉冲 (N=10-1500) λ=343 nm、515 nm（前两个波长均为 1.40 J/cm2）和 1030 nm（1.70 J/cm2）激光照射下的响应。40 J/cm2）和 1030 nm（1.70 J/cm2）的多脉冲（N=10-1500）激光，研究了吸收机制如何影响这些材料的加工效率。在恒定通量和脉冲数的条件下，通过改变重复率实现了可调烧蚀深度和直径。研究结果凸显了吸收机制、重复率范围和材料热特性对提高烧蚀效率的作用。此外，使用高重复率可改善激光加工，减少扩展热效应，提高烧蚀均匀性。

The role of absorption mechanism on the optimization of processing commercial polymers under high repetition rate femtosecond laser irradiation

The response of three of the most used commercial polymers (poly(vinyl chloride) (PVC), poly(ethylene terephthalate) (PET) and polypropylene (PP)) under irradiation with high repetition rate (1 kHz-1 MHz) femtosecond (450 fs) multi-pulse (N=10-1500) laser at λ=343 nm, 515 nm (1.40 J/cm2 for both former wavelengths) and 1030 nm (1.70 J/cm2) is reported, obtaining a study on how the absorption mechanism influences the processing efficiency for these materials. Tunable ablation depth and diameters are accomplished by modifying repetition rates at a constant fluence and number of pulses. The results highlight the role of absorption mechanism, repetition rate ranges and thermal properties of the materials for benefiting ablation efficiency. Furthermore, the use of high repetition rates improves the laser processing, reducing extended thermal effects and increasing ablation uniformity

期刊介绍： Rapid progress in optics and photonics has broadened its application enormously into many branches, including information and communication technology, security, sensing, bio- and medical sciences, healthcare and chemistry. Recent achievements in other sciences have allowed continual discovery of new natural mysteries and formulation of challenging goals for optics that require further development of modern concepts and running fundamental research. The Journal of the European Optical Society – Rapid Publications (JEOS:RP) aims to tackle all of the aforementioned points in the form of prompt, scientific, high-quality communications that report on the latest findings. It presents emerging technologies and outlining strategic goals in optics and photonics. The journal covers both fundamental and applied topics, including but not limited to: Classical and quantum optics Light/matter interaction Optical communication Micro- and nanooptics Nonlinear optical phenomena Optical materials Optical metrology Optical spectroscopy Colour research Nano and metamaterials Modern photonics technology Optical engineering, design and instrumentation Optical applications in bio-physics and medicine Interdisciplinary fields using photonics, such as in energy, climate change and cultural heritage The journal aims to provide readers with recent and important achievements in optics/photonics and, as its name suggests, it strives for the shortest possible publication time.
