Mechanisms in an argon ion pulsed laser
(University of St Andrews, 1968) - ThesisAlthough 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
(University of St Andrews, 2005) - ThesisThe 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 ... -
Theory of high power electron cyclotron resonance heating
(University of St Andrews, 1988) - ThesisElectron cyclotron resonance heating has been successfully used on a series of experiments in an attempt to raise plasma temperatures beyond the constraints of the resistive dissipation which occurs with ohmic heating. ... -
Continuous-wave, intracavity singly-resonant optical parametric oscillators based upon Nd-doped laser gain media
(University of St Andrews, 2003) - ThesisThis thesis describes a system which overcomes one of the limitations faced by traditional continuous-wave optical parametric oscillators (cw OPOs). In this approach the high circulating field found within a laser cavity ... -
Electroluminescence and switching phenomena in ZnSe Schottky diodes
(University of St Andrews, 1973) - Thesis
