    • The kinetics of copper HyBrID lasers 

      Whyte, Colin (University of St Andrews, 1996-07) - Thesis
      Spatially and temporally resolved measurements of many of the parameters of a 25mm bore, 800mm active length copper HyBrID laser have been performed. The laser was operated under excitation conditions for maximum efficiency ...

    • Ion processes and effects in CO₂ laser discharges 

      Shields, Henry (University of St Andrews, 1987) - Thesis
      Presently, a major factor restricting the achievement of higher power outputs from the CO2 laser is the occurrence of plasma instability. This instability may manifest itself in two forms causing either discharge striations ...

    • Heat transfer studies of strontium recombination lasers 

      Pugsley, Trevor R. (University of St Andrews, 1995-07) - Thesis
      Thermal loading models have been developed in order to predict the optimum input powers of free-convection cooled strontium recombination lasers (SRLs) and forced-convection cooled SRLs. Gas temperature models have also ...

    • Tunable femtosecond lasers with low pump thresholds 

      Oppo, Karen (University of St Andrews, 1996-07) - Thesis
      The work in this thesis is concerned with the development of tunable, femtosecond laser systems, exhibiting low pump threshold powers. The main motive for this work was the development of a low threshold, self-modelocked ...

    • Development of all-solid-state modelocked laser sources at 1.55 μM 

      Valentine, Gareth J. (University of St Andrews, 1999-03) - Thesis
      This thesis concerns the generation of tunable ultrashort pulses near the 1.55 mum telecommunications window. Two principal laser systems are considered: i) the NaCl:OH colour-centre laser, which employs the technique of ...
