    • Optical spanners and improved optical tweezers 

      Simpson, Neil B. (University of St Andrews, 1998-03) - Thesis
      This thesis describes the experimental and theoretical work that investigated the transfer of orbital angular momentum from light to matter. This was achieved by combining two established areas of laser physics which were ...

    • Optimisation of a colliding-pulse modelocked dye laser 

      Williams, Edmond J. O. (University of St Andrews, 1998-05) - Thesis
      The work presented in this thesis describes the operation, characterisation and optimisation of a colliding-pulse modelocked (CPM) dye laser. A method of pulse analysis has been developed which is capable of determining ...

    • Investigations on two-level maser oscillations 

      Firth, Ian Mason (University of St Andrews, 1962) - Thesis
      Abstract Not Provided

    • 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 ...
