Abstract

1,249,906. Lasers. COMPAGNIE GENERALE D'ELECTRICITE. 29 May, 1969 [10 June, 1968], No. 27234/69. Heading H1C. A cylindrical optical pumping reflector 7, Fig. 1, conforms in section to a pair of ellipses produced from a common focus, a pumping lamp 5 being located at the common focus and a separate active medium 1, 3 being located at each of the outer foci. Mirrors 15, 17, Fig. 2, may be provided so that the two active media operate in series in a single resonator formed by mirrors 11, 13. One active medium may alternatively function as a generator and the other as an amplifier. Alternatively the two media may produce separate outputs.
