  • Mixed silicates of yttrium and lanthanide and laser using monocrystals of these silicates
    Patent number: 5173911
    Abstract: Mixed silicates of yttrium and lanthanide and laser using monocrystals of these silicates. The laser has a laser cavity (2) containing as the light emitter a monocrystal (4), means (12,14) for amplifying the light from the monocrystal, means (14) for removing light from the laser cavity and optical pumping means (6), characterized in that the monocrystal is of formula (I):Y.sub.2-2x-2y M.sub.2x Yb.sub.2y SiO.sub.5 (I)in which M represents a lanthanide chosen from among erbium and thulium and x and y represent numbers such that 0<x.ltoreq.0.2 and 0<y.ltoreq.0.2.
