• Monitoring of Vapor Uptake by Refractive Index and Thickness Measurements in Thin Films 

      Chen, Weijian; Saunders, John E.; Barnes, Jack A.; Yam, Scott S.-H.; Loock, Hans-Peter (2016-03-04)
      We report a method for real-time monitoring of vapor uptake by simultaneous detection of the refractive index, 𝑛 , and thickness, 𝑑 , of thin transparent films with a precision of 𝛿𝑛=10 −4 and 𝛿𝑑<100  nm . The setup ...

      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 ...
