摘要：

The effect of the reduced argon atmosphere on the self-absorption of a spectrum was studied with the use of a normal laser microprobe by changing the gas pressure and the observation height of spectral lines. At 150 Torr, a spectral line virtually free of self-absorption and a resultant high emission intensity were obtained about 1.5 mm above the sample surface. Using this condition, the linear calibration curve with unit slope was obtained for the analysis of copper (concentration:1–20%) in aluminium samples. © 1990 The Japan Society of Applied Physics.
