ABSTRACT:
To alleviate the adverse thermal effects of the pumping power and to increase the efficiency of the laser, a solid state laser rod is formed of a polygonal cross-section having flat, internally reflecting side surfaces extending parallel to the rod axis. A light beam applied to one end surface describes an angluar helical path within the rod to a second end surface. By passing the light beam through diverse areas of the rod, compensation for radial temperature gradients is obtained. A plurality of laser beams may traverse the rod.
