摘要

脉冲激光烧蚀靶是制备金属纳米粒子的一个很有前途的方向，在各种科学、技术和生物医学应用领域都有广泛的应用。为了改进激光技术，必须控制烧蚀过程，确保所得到的纳米颗粒的必要尺寸分布，这些纳米颗粒通常是双峰的。这项工作提出了一种方法，允许人们通过扫描电子显微镜（SEM）图像或金属薄膜中孔的显微照片的短脉冲来估计激光烧蚀过程中纳米颗粒部分的质量。利用纳秒级激光脉冲和厚度为50 nm的金膜进行研究。

Nanoparticles in Laser Ablation: Fractions

The pulsed laser ablation of targets is a promising direction for creating metal nanoparticles that are widely used in various fields of science, technology, and for biomedical applications. To improve laser technologies, it is necessary to control the ablation process, ensuring the necessary size distribution of the resulting nanoparticles, which is often bimodal. The work proposes an approach that allows one to estimate the mass of the nanoparticle fraction during laser ablation with short pulses from a scanning electron microscopy (SEM) image or microphotograph of holes in a metal film. The investigation is carried out using nanosecond laser pulses and gold films 50 nm in thickness.
