Abstract

1,016,776. Lasers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 12, 1964 [June 17, 1963], No. 23944/63. Heading H3B. A laser using doped glass; as the active medium is] pumped by the output from one or more semi-conductor lasers. The active medium may comprise " Kodial " glass containing neodymium, in the form of a rod 1 having plane reflecting end surfaces 2, 3 one of which is partially transmitting. Optionally one end surface may be inclined for " spoilt Q " operation. Pumping is effected by a plurality of semi-conductor diode lasers 4 secured to the glass surface and provided with electrodes 5, 6 and reflecting surfaces 8, 9, defining optical cavities. A layer 10 of electricallyinsulating material is interposed between each semi-conductor and its reflecting surface 8 when the reflector is metallic. The reflecting surfaces 9 are polished and metallized planes of the glass. The semi-conductor diodes and the glass have the same expansion coefficient and are secured together by glazing the semiconductors on the contacting surface and then pressing the semi-conductors against the glass at a temperature at which the glass surface is molten. Gallium arsenide diodes are used for operation at normal temperatures and diodes formed of an alloy of gallium and indium arsenides are used at a temperature of 77‹ K.
