激光诱导钛合金等离子体电子温度和电子密度的时间分辨测量
Time-Resolved Measurements of Electron Temperature and Electron Density in Laser-Induced Titanium Alloy Plasma
摘要
Abstract
The time-resolved emission spectra of laser-induced titanium alloy plasma was obtained using a mid-level echelle spectrometer nanosecond and an intensified charge-coupled device(ICCD),with a 532 nm nanosecond pulse laser as the excitation source.The electron temperature of the plasma was calculated using the Boltzmann plot method and the Saha-Boltzmann plot based on the emission spectra,and the electron density was determined by the Stark broadening method.The results show that the Saha-Boltzmann plot could provide more accurate calculations of the electron temperature compared to the Boltzmann plot.Additionally,an increase of the spectral gate width would lead to a decrease in the calculated values of electron temperature and electron density.The results provide experimental guidance for laser-induced breakdown spectroscopy(LIBS)analysis of titanium alloys.关键词
