| abstract | 1,138,338. Laser glass compositions. AMERICAN OPTICAL CO. 29 Nov., 1965 [22 Dec., 1964], No. 50513/65. Heading C1M. [Also in Divisions C4 and H1] A laser includes rare-earth sensitizer ions and laser ions in a glass host material (see Division H1). In one embodiment trivalent erbium is used as a laser ion and trivalent ytterbium as a sensitizer in a glass host material comprising 15% ytterbium oxide, % erbium oxide, 70À64% silicon oxide, 7À58% sodium oxide, 11À47% potassium oxide, 5À05% barium oxide, 1À05% antimony oxide, 1À58% aluminium oxide, 1À58% zinc oxide and 1À05% lithium oxide. The percentages given are weight per cents. Other glass hosts in which the ytterbium and erbium are used may be silicates, phosphates, borates, borosilicates, arsenic trisulphide, selenides, tellurides and other chalcogenics, fluorides, oxi-fluorides, aluminosilicates and germanates. Neodymium may also be used as a pump ion in addition to the ytterbium, and trivalent thulium or holmium may be used as laser ions, in which case ytterbium and erbium, and ytterbium, erbium and thulium are used as pump ions respectively. Reference has been directed by the Comptroller to Specification 1,015,057. |
