  • High-power solid-state laser
    Patent number: 7058102
    Abstract: A device for producing laser radiation, the device comprising: an elongate sample of a quasi-three-level laser material; a source of pumping radiation; and a concentrator configured such that at least some of the pumping radiation emitted by the source of pumping radiation is concentrated by the concentrator and subsequently enters the sample through a side surface thereof.
    Type: Grant
    Filed: September 18, 2001
    Date of Patent: June 6, 2006
    Assignee: DSO National Laboratories
    Inventors: Poh Boon Phua, Kin Seng Lai, Rui Fen Wu, Yuan Liang Lim, Wei Pin Ernest Lau
  • Tm:YAG laser
    Patent number: 6859480
    Abstract: A device for producing laser radiation having a wavelength of about 2 ?m, the device comprising: a solid-state sample capable of producing lasing transitions corresponding to a wavelength of about 2 ?m; and a source of pumping radiation having a wavelength of about 1 ?m, the source being arranged so that at least some of the radiation produced thereby is absorbed by the solid-state sample, causing the solid-state sample to emit radiation having a wavelength of about 2 ?m.
    Type: Grant
