这几天看到一篇德国的论文，讲的是用激光照射咖啡粉从而模拟冷萃咖啡，感觉很有意思。但是他这个没有说明用的激光器的型号，只是给了大致的参数，有没有大佬能通过参数看看用什么激光器比较合适？或者有对应的型号？

论文名称：Ultrafast cold-brewing of coffee by picosecond-pulsed laser extraction

原文：Commercially roasted and ground coffee beans (Coffee Pirates, Costa Rica SHB EP Tarrazú, 100% Arabica) were used as a starting material. The time between roasting and experiments was 10 days. The pulsed laser irradiation of 1.65 g coffee powder dispersed in 30 mL ultrapure water was performed with an Nd-YAG-laser centered at 532 nm. A ps-laser (Edgewave) with a pulse duration of 10 ps, a repetition rate of 80 kHz, and pulse energy of 125 μJ was used in the experiments. The fragmentation experiments were carried out in a small vessel equipped with a stirring system. The schematic procedure is shown in Fig. 6. To remove excess coffee powder from the samples after laser fragmentation, commercially available coffee filters were used (Kaufland TIP, coffee filters, size 4). Please note that some filter ingredients can be flushed into the final coffee product. We included a filter step in all variants productions to keep good comparability between the different coffee variants.

作为起始材料，本研究采用商业烘焙并研磨的咖啡豆（品牌：Coffee Pirates，产地：哥斯达黎加SHB EP Tarrazú，100%阿拉比卡种）。咖啡豆烘焙与实验间隔时间为10天。实验中将1.65克咖啡粉末分散于30毫升超纯水中，使用中心波长532 nm的掺钕钇铝石榴石（Nd-YAG）脉冲激光进行辐照处理。具体实验参数为：皮秒激光器（Edgewave）输出脉冲宽度10 ps，重复频率80 kHz，单脉冲能量125 μJ。破碎实验在配备搅拌系统的小型容器中进行，实验装置示意图见图6。

激光破碎处理后，使用市售咖啡滤纸（Kaufland TIP咖啡滤纸，4号尺寸）去除样品中多余的咖啡粉末。需特别说明的是，部分滤纸成分可能迁移至最终咖啡产物中。为确保不同咖啡变体间的良好可比性，本研究在所有变体制备流程中均统一设置了过滤步骤。
