This paper dealt with the focusing characteristics of the beam, of which divergent angle was very large in comparison with the diffraction limitted one. In this analysis it was assumed that the beam radiated from a point diverged in a corn like shape of which axis was in the radiated direction, and that its beam energy density in the plane perpendicular to the axis was given by Gaussian curve. Mathematical fomulations which gave power density of the focused beam were expressed in the nondimensional form, and the calculated values were compared with experimental data obtained from CO₂ laser beam of which divergent angle was 4-5 times the diffraction limitted one. It was shown that both were considerably coincidental. The agreement between calculated values and experimental data obtained from electron beam was also satisfactory but was not so good as the case of CO₂ laser.
