A method of spectrochemical analysis by means of G.P. (giant pulse) laser has been applied to the analysis of C, Si, Mn in solid steel and its most suitable condition has been studied. The following results have been obtained : (1) In atmosphere of the analysis, Ar or Ar+3%H_2 is better than N_2 and air from the point of view of spectral intensity and SN ratio. (2) As a result of examinations of influence of laser energy on spectral intensity and intensity ratio, it is generally suitable to set up laser energy above 0.3J. And for the purpose of minimization in variations of each analysis, intensity ratio to Fe II 271.4nm should be used. (3) In the most suitable condition described above, calibration curves have been made and its relative errors of analysis have been evaluated. (4) As a result of the time profile studies of the spectral lines obtained in Ar atmosphere, it has been shown that the separation of line and background is possible, and so that SN ratio of the analysis is much improved by this technique.
