Abstract
In this paper, a nonplanar ring laser operating at has been proposed and demonstrated by using a specially designed Porro prism together with a commercially available corner cube prism. An Nd:YAG with a shape of scalene right triangle and an undoped YAG are thermally bonded to fabricate the novel composite Porro prism. A magnetic field providing the nonreciprocal Faraday rotation is applied to the corner cube prism, which gives flexibility in choosing magneto-optic materials. The operating principle of single-frequency operation for this ring laser is illustrated in detail. A maximum continuous output power of was achieved when the laser operated stably on the single axial mode. single-frequency operation with has also been demonstrated by intracavity doubling with crystal.
