Effect of laser energy and atmosphere on the emission characteristics of laser-induced plasmas. Kuzuya, M., Matsumoto, H., Takechi, H., & Mikami, O. Applied Spectroscopy, 47(10):1659-1664, 1993.
abstract   bibtex   
The effects of laser energy and atmosphere on the emission characteristics of laser-induced plasmas were studied with the use of a Q-switched Nd:YAG laser over a laser energy range of 20 to 95 mJ. Argon, helium, and air were used as surrounding atmospheres, and the pressures were changed from atmospheric pressure to 1 Torr. The experimental results showed that the maximum spectral intensity was obtained in argon at around 200 Torr at a high laser energy of 95 mJ, whereas the line-to-background ratio was maximized in helium at around 40 Torr at a low energy of 20 mJ. The results are discussed briefly on the basis of the temporal and spatial observations of the laser-induced plasmas.
