    • Improved Temporal Stability of Polymethine Laser Dyes in Aqueous Solutions 

      Hackett, C.E.; Dewey, C.F. Jr (Institute of Electrical and Electronic Engineers, 1973)
      Polymethine laser dyes which fluoresce in the near infrared in organic solvents generally exhibit poor temporal stability at room temperature. Two typical laser-pumped polymethine dyes in aqueous solutions containing ...

    • Lasing Efficiency and Photochemical Stability of IR Laser 

      Oettinger, Peter E.; Dewey, C. Forbes Jr (Institute of Electrical and Electronic Engineers, 1976)
      The lasing efficiencies and photochemical stabilities of laser dyes useful in the 710-1080-nm spectral region have been investigated using a Q-switched ruby laser pumping source. The measured bleaching rates P defined ...

    • Pressure Dependence of the Infrared Laser Lines in Barium Vapor 

      Madigan, M.; Hocker, L.O.; Flint, J.H.; Dewey, C.F. Jr (Institute of Electrical and Electronic Engineers, 1980)
      We have studied nine laser transitions in Ba vapor at wavelengths between 1.13 and 3.05 micrometer. Three of these laser lines have not been reported previously. The relative intensities of the four strongest transitions ...
