Radiofrequency analysis using optical signal processing
(University of St Andrews, 1991-07) - ThesisThe basic form of conventional electronic and acoustooptic radiofrequency spectrum analysers is described. The advantages and disadvantages of the various systems are discussed with particular reference to radar signal ... -
Ultrafast electron-optical visible / X-ray-sensitivity streak and framing cameras
(University of St Andrews, 1990-07) - ThesisIn this thesis the development of ultrafast electron-optical streak and framing cameras having radiation sensitivities ranging from the visible to soft X-ray are discussed. A framing camera incorporating a vacuum demountable ... -
An all-solid-state optical parametric oscillator for the infrared
(University of St Andrews, 1994-07) - ThesisA low threshold, efficient optical parametric oscillator (OPO) based on the material Potassium Titanyl Phosphate (KTP) and pumped by a diode-laser-pumped, Q-switched Nd:YLF laser has been demonstrated and investigated. ... -
Oxygen and its control over structural and electronic properties of Pb based 1212 superconductors
(University of St Andrews, 1998-02) - ThesisThe phase stability, electronic properties and crystal structure of the Pb based 1212 cuprate superconductor (Pb[1+x]/2Cu[1-x]/2)Sr2(Y1-xCax)Cu2O7+/-s were studied using a number of techniques. Since synthetic difficulties ... -
High spatial and spectral quality diode-laser-based pump sources for solid-state lasers and optical parametric oscillators
(University of St Andrews, 1999-09) - ThesisIn this thesis the use of high spatial- and spectral-quality diode-laser pump sources for solid-state lasers and continuous-wave optical parametric oscillators (cw OPOs) is investigated. While diode lasers are potentially ...
