Abstract

In this work, the profiles of craters obtained by the irradiation of a picosecond laser with a wavelength of 1064 nm and energy density in the range of 0.4–7.0 J/cm² of tungsten films were measured using energy-dispersive X-ray spectroscopy, as well as a contact profilometry. The presence of several mechanisms of surface erosion at given irradiation parameters is shown. The influence of the craters shape on the signal of laser-assisted quadrupole mass spectrometry during irradiation of deuterium-containing tungsten films is analyzed.

皮秒激光脉冲辐照钨膜表面凹坑分析

本文采用能量色散x射线能谱法和接触轮廓法测量了波长为1064 nm、能量密度为0.4 ~ 7.0 J/cm2的皮秒激光照射下的撞击坑轮廓。在给定的辐照参数下，存在几种表面侵蚀机制。分析了在含氘钨薄膜辐照过程中，弹坑形状对激光辅助四极杆质谱信号的影响。

期刊介绍： Physics of Atomic Nuclei is a journal that covers experimental and theoretical studies of nuclear physics: nuclear structure, spectra, and properties; radiation, fission, and nuclear reactions induced by photons, leptons, hadrons, and nuclei; fundamental interactions and symmetries; hadrons (with light, strange, charm, and bottom quarks); particle collisions at high and superhigh energies; gauge and unified quantum field theories, quark models, supersymmetry and supergravity, astrophysics and cosmology.
