Abstract
1,046,546. Lasers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 26, 1964 [March 26, 1963], No. 7909/64. Heading H3B. A solid state laser comprises a resonant cavity defined by a pair of parallel reflecting surfaces and an optical system adapted to accept at least part of the light output and to reflect at least part back into the resonant cavity. In the arrangement of Fig. 1 (not shown) the resonant cavity is formed by the silvered end of an optically pumped ruby and a partially reflecting external plane mirror. Light from the cavity is focused by a convex lens on to a partially transmissive plane mirror so that a substantial portion of the output light is reflected back into the cavity. In Fig. 2 a ruby crystal 40 positioned in a pumping cavity 42 provided with four pumping lamps 44 has one end 46 silvered and the other end 48 uncoated. The resonant cavity is formed by face 46 and the flat coated face of field lens 54 of a movable Ramsden eyepiece of a microscope. Field lens 54 and eye lens 56 form the optical system which reflects light back.
