Abstract

PURPOSE:To use all incident light beams as output light beams except a little absorption loss of a mirror, by providing a total reflection mirror arranged opposite on a half mirror so that the second light beam can be reflected in the same direction as the first light beam emitted in a desired direction, among the light beams emitted in two first and second directions from the half mirror. CONSTITUTION:As for light beams emitted in two first and second directions from a half mirror 4, the light beam in the second direction is reflected in the same direction as the light beam in the first direction by a total reflection mirror 14. That is, light beams, 5, 6 emitted from laser oscillators 1, 2 are all transmitted effectively except an absorption loss by the mirror, as light beams 8, 9 and light beams 12, 13. This effect is obtained in the same way in case two pieces or more of laser oscillators are provided, as well. In such a way, all incident light beams except a little absorption loss in the mirror can be used as emitted light beams.
