  • Composite polymer-glass edge cladding for laser disks
    Patent number: 4849036
    Abstract: Large neodymium glass laser disks for disk amplifiers such as those used in the Nova laser require an edge cladding which absorbs at 1 micrometer. This cladding prevents edge reflections from causing parasitic oscillations which would otherwise deplete the gain. Nova now utilizes volume-absorbing monolithic-glass claddings which are fused at high temperature to the disks. These perform quite well but are expensive to produce. Absorbing glass strips are adhesively bonded to the edges of polygonal disks using a bonding agent whose index of refraction matches that of both the laser and absorbing glass. Optical finishing occurs after the strips are attached. Laser disks constructed with such claddings have shown identical gain performance to the previous Nova disks and have been tested for hundreds of shots without significant degradation.

  • Low temperature reversion resistant organosilicon polymers
    Patent number: 3975362
    Abstract: Polymers which are flexible down to -40.degree.F. and which do not depolymerize appreciably when heated in a closed space at 500.degree. F. or above have the structure ##EQU1## These polymers can be cured to rubbers which are solvent resistant and are flexible over a wide temperature range. Such rubbers are useful for sealing aircraft fuel tanks.
