Abstract

PURPOSE:To control the lowering of laser power to be minimum due to holding the divergence angle of the laser beam to be small by making the radius of curvature of a partial reflector for picking up power larger than any radius of curvature of a total reflector for turning. CONSTITUTION:The radius of curvature of total reflectors M1-Mn are equal to rm, and the radius of a partial reflector 12 for picking up power is rw. The relation of them is rw>rm. The beam diameter and divergence angle of the laser beam picked out from the partial reflector 12 mainly depend on the distance between a total reflection angle Mn and the partial reflector mirror 12 and their radii, so that the distance between the total reflectors M1 and Mn-1 and their radii are unnecssary to consider. For example, in case where the radius of curvature of the total reflector is 5m, only the partial reflector is plain, the size of the total reflector is 25.4mm., and the laser tube diameter is 16.8mm., the divergence angle is 3.2m rad. When the radius of curvature of the partial reflector is made layer, the diffraction loss can be made minimum, the transverse mode is made a single one, and the divergence angle is made smaller.
