抄録(英) Hydrogen emission has been studied in laser plasma by focusing a TEA CO2 laser (10.6 μm, 500 mJ, 200 ns) and a Nd-YAG laser (1,064 nm, 50 mJ, 8 ns) on various types of samples, such as glass, quartz, copper plate, zinc plate and zircaloy pipes doped with hydrogen. It was found that H_α emission with a narrow spectral width occurs with high efficiency when the laser plasma is produced in the low-pressure region. In contrary, the conventional well-known laser-induced breakdown spectroscopy (LIBS), which usually made at atmospheric air pressure, cannot be applied for the analysis of hydrogen as impurity. This specific characteristic of hydrogen emission is interpreted based on our shock wave model, taking account of the fact that the hydrogen mass is extremely light compared to that of the host elements.
