THE PHENOMENON OF GENERATION BY A CIRCULAR CYLINDER AND A SPHERE.
Abstract
The problem of stimulated electromagnetic wave emission from a circular cylinder and a sphere is investigated theoretically on the basis of Maxwell's equations. In particular, it is shown that radiation similar to that of a sphere should occur on the lateral surface of a cylinder. This radiation, since it is not used, is a source of additional energy losses and reduces the efficiency of a laser. These losses should not appear in a gaseous laser nor when the lateral wall of a cylinder with a refractive index greater than in the active medium is enclosed in a dielectric. Transverse-electric modes are considered; all the computations are the same for transverse-magnetic modes. (Author)
