• Near Infrared Absorption Detection in Picolitre Liquid Volumes Using Fiber Loop Ring-Down Detection 

      Andrews, Nicholas L. P.; Litman, Jessica; Stroh, Daniel; Barnes, Jack A.; Loock, Hans-Peter (2016-03-07)
      Cavity ring-down spectroscopy is performed using a single-mode fibre loop as an optical cavity. The loop contains absorption cells for either liquids or gases, as well as an erbium-doped fibre amplifier. The fibre amplifier ...
    • Quantification of Different Water Species in Acetone using a NIR-Triple-Wavelength Fiber Laser 

      Andrews, Nicholas L. P.; MacLean, Amy G.; Saunders, John E.; Barnes, Jack A.; Loock, Hans-Peter; Saad, Mohammed; Jia, Chenglai; Ramaswamy, Kishor; Chen, Lawrence R. (2016-02-25)
      A fiber laser using a thulium-doped ZBLAN gain medium was used to generate laser radiation simultaneously at 1461, 1505 and 1874 nm, with > 5 mW output power at each of the wavelengths. The laser was used to quantify the ...
    • Three-Wavelength Tm3+:ZBLAN Fiber Laser and its Applications in Water Detection 

      Jia, Chenglai; Ramaswamy, Kishor; Chen, Lawrence R.; MacLean, Amy G.; Andrews, Nicholas L. P.; Saunders, John; Barnes, Jack A.; Loock, Hans-Peter; Saad, Mohammed (2016-02-25)
      We demonstrate a three-wavelength Tm3+:ZBLAN fiber laser emitting simultaneously at 1460 nm, 1503 nm, and 1873 nm and its application in single-pass absorption measurements for detecting and quantifying water concentration ...
