Abstract
A laser beam generator has a pair of opposing mirrors. A reflecting surface of at least one of the opposing mirrors is constituted by a conical surface having a vertex angle of 90 degrees in order to tangentially polarize a laser beam. This conical surface is diverged toward the other opposing mirror at an angle of 45 degrees with respect to an optical axis from its vertex held alignment with the optical axis.
