Abstract
986,042. Light guide. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. June 17, 1963 [June 20, 1962], No. 24013/63. Heading G2J. [Also in Division H3] Light from a source 25, Fig. 2, is transmitted from the thick end 26 to the thin end 23 of a wedgeshaped light conductor 20 by reflection between the converging surfaces 21, 27, the transmitted light being emitted at a side face of the conductor adjacent the thin end where it activates an optical maser or a thermistor bolometer. As applied to an optical maser, the light source 25 may be an Xenon discharge tube, a potassium vapour lamp or a high pressure mercury vapour lamp. The light conductor 20 is formed of heavy flint glass with a refraction index of 1. 9, and the thick end 26 may have either a plane or a convex surface. Fig. 1 shows the light conductor in end elevation, in association with the active medium 1 of an optical maser consisting of uranium or samarium activated calcium fluoride or chromium activated ruby formed with right prism end reflecting surfaces 2, 3. The coherent light output is obtained through a further prism 14 which is spaced from prism 3 by a layer 15 of low refractive index, the layer being air if the active medium is ruby and the prism 14 is silicon, and MgF 2 if the active medium has a higher refractive index than ruby. The layer has a thickness of about 5000 A if of air to give a reflection-transmission ratio of about 100: 1. A mirror 16 may be provided against one face of the prism 14 to obtain an emerging beam in only one direction. A modification is shown in Fig. 3 for use where the active medium 30 has poor absorption of the pumping radiation, the emergent light from the conductor 20 being reflected between the axial faces of the active medium as it transverses the length of the body. In this embodiment one end 32 of the medium is plane and partially transparent. A radiation sensitive device is shown in Fig. 4 in which a thermistor bolometer 40 is associated with a light conducting wedge 41 having one surface 42 curved to approximate to the arc of a circle.
