    • Novel optical micromanipulation techniques and applications of violet diode lasers 

      Carruthers, Antonia E. (University of St Andrews, 2005) - Thesis
      In this thesis, optical micro-manipulation experiments are described using laser sources spanning the wavelength region 1064 nm to 410 nm. Optical guiding is studied at near infrared wavelengths (780 nm) for comparison of ...

    • Optical manipulation and the angular momentum of light 

      O'Neil, Anna T. (University of St Andrews, 2002) - Thesis
      This thesis consists primarily of an investigation into the action of laser light on particles held within optical tweezers. I present work on a dynamic method of measuring both the axial and lateral efficiencies of optical ...

    • The frequency stabilization of gas lasers 

      Wallard, Andrew John (University of St Andrews, 1972) - Thesis
      This thesis contains a description of the design and development of a visible helium-neon laser stabilized to an absorption transition in an intracavity cell of iodine vapour. Two methods of frequency locking the laser ...

    • Mechanisms in an argon ion pulsed laser 

      Taylor, Andrew Ramage (University of St Andrews, 1968) - Thesis
      Although many argon ion lasers, both pulsed and D.C., have been built and used, the mechanisms which cause the required population inversion in the gas are still doubtful, and different views are held by different workers ...

    • Dynamical optical nonlinearities in semiconductor optical amplifiers and quantum cascade lasers 

      Gomez-Iglesias, Alvaro (University of St Andrews, 2005) - Thesis
      The ultrafast dynamics in semiconductor optical amplifiers (SOAs) relevant to all-optical switching have been studied by means of time-resolved spectroscopic experiments on a multiple quantum well InGaAs amplifier. The ...
