Holographic lasers
This thesis presents the development of CW adaptive solid state lasers which dynamically correct for phase distortions within their cavity by phase conjugation. A fibre based four-wave mixing scheme is investigated but no experimental evidence of any phase conjugation is observed.

Holographic laser resonators
The work presented within this thesis details the development and characterisation of a CW solid-state adaptive resonator that uses phase-conjugation to actively correct for phase distortions present within the resonator loop. It is shown that the phase-conjugate of a given beam can be produced by …

Gas-sensitive holographic sensors
Holographic sensors are photonic layered structures contained in analyte sensitive lms that upon illumination produce monochromatic reflections (λ). The present work reports the fabrication of oxygen and ammonia sensors in Nafi on membranes and hydrocarbon and volatile organic compound sensors in …

A study of holographic superconductors
… thoroughly investigated. We observe that the holographic superconductors can be consistently classified into two, based on the scaling dimensions and the charge of the dual condensates. Holographic superconductors of dimension λ- exhibit features of type II superconductors while those of …

Digital holographic imaging of microorganisms
… natural environments. In this research, digital holographic imaging (DHI), with a 4f system providing transverse magnification of 9.1, is used to study such microorganisms. To test the imaging technique, DHI was used to locate and track 10 micrometer Dunaliella freely swimming in a 30 milliliter …

Emergent Times in Holographic Duality
In holographic duality an eternal AdS black hole is described by two copies of the boundary CFT in the thermal eld double state. In this thesis we provide explicit constructions in the boundary theory of infalling time evolutions which can take bulk observers behind the horizon. The constructions …
