    • Stellar photometry from above the earth's atmosphere 

      Campbell, J. W. (University of St Andrews, 1980) - Thesis
      Although relative ground based stellar photometry has been an established investigative technique for many years, there have been very few programmes which have provided absolute stellar fluxes and indeed where such results ...

    • Atomic laser-spectroscopy in the UV and visible 

      Kane, D.M. (University of St Andrews, 1984-07) - Thesis
      This thesis describes the development of an intracavity frequency doubled dye laser from a commercial Spectra-Physics 380D single frequency ring dye laser, and the application of this system to a number of spectroscopic ...

    • A unified state variable analysis of repetitively pulsed recombination lasers 

      Kidd, Andrew Keith (University of St Andrews, 1992-07) - Thesis
      A unified state-space model of a high repetition rate electrical discharge in a helium-strontium mixture is presented. The atomic (number density of particles in a particular state), optical (number density of photons), ...

    • Kinetic modelling of fundamental (00̊1) and sequence (00̊2) band CO₂ lasers 

      Mellis, John (University of St Andrews, 1984-07) - Thesis
      The vibrational kinetics of the CO2 laser system are studied experimentally and theoretically. A sequence (00°2) band/ fundamental (00°1) band gain ratioing technique is used to measure the CO2 asymmetric stretch ...

    • Some aspects of nonlinear laser plasma interactions 

      Johnson, David A. (University of St Andrews, 1995-07) - Thesis
      Recent advances in the development of high power short pulse laser systems has opened a new regime of laser plasma interactions for study. The thesis is presented in two parts. In Part I, we consider the implications of ...
