    Armistead, C.J. (University of St Andrews, 1987-07) - Thesis
    An optically pumped far-infrared laser and superconducting magnet have been used to perform high resolution studies of the energy levels of neutral and negatively charged shallow donors in high purity n-GaAs and n-InP in ...

  • Microwave excited copper halide and strontium-ion recombination lasers 

    Bethel, James W. (University of St Andrews, 1995-07) - Thesis
    Microwave excitation of pulsed metal vapour lasers (copper halide and strontium-ion recombination lasers) is investigated. Two waveguide coupling structures were designed and built, one based on a ridge waveguide; and the ...

  • DC glow discharge electron guns for the excitation of rare gases / R.J. Carman. 

    Carman, R.J. (University of St Andrews, 1986-07) - Thesis
    Glow discharge electron guns are used to generate continuous electron beams at 0.5keV-3.0keV in the intermediate range of gas pressures (0.1mb-10.0mb). Cathodes incorporating internal cavities are used to generate distinct ...

  • Optical parametric oscillators pumped by excimer lasers 

    Ebrahimzadeh, Majid (University of St Andrews, 1990-07) - Thesis
    This thesis describes the development of a new generation of pulsed optical parametric oscillators (OPO's) based on two new non-linear materials, urea and beta-BaB2O4 (or BBO), and pumped by a new class of laser pump ...

  • Microwave excitation of argon ion and helium-krypton ion lasers 

    Dobie, Paul J. (University of St Andrews, 1989-07) - Thesis
    Pulsed microwave excitation of noble gas ion lasers at frequencies between 3 and 17 GHz is investigated. The advantages of using microwaves instead of conventional DC sources to pump a laser are explained. These include ...
