Abstract
Abstract An optical molecular amplifier (laser) including a mirror system forming a closed cavity having the configuration of a prolate ellipsoid of revolution, a luminous pump source disposed on a transverse axis of the ellipsoid at one focal point thereof, and an excitable material disposed on the transverse axis of the ellipsoid at the other focal point thereof. The closed cavity forming the pump reflector mirror system includes a pair of superposed semiellipsoidal bowls joined along a conjugate axis of the ellipsoid of revolution to form a hermetic seal therebetween. A pair of oppositely disposed flanges are adhered to both longitudinally disposed apex end portions of the closed cavity, and each flange is formed with an aperture passing therethrough disposed coaxially of the transverse axis of the ellipsoid of revolution. The luminous pump source and the excitable material are disposed concentrically within a cylindrical, Dewarlike cooling tube arranged along the transverse axis of the ellipsoid of revolution and supported within the apertures formed in the pair of flanges. The pump reflector including the pair of flanges and the cooling tube which supports the luminous pump source and the excitable material are supported within and encircled by a cylindrical housing disposed coaxially of the transverse axis of the ellipsoid of revolution and provided with closed end portions to form a cavity for receiving a coolant.
