The Diode Laser Source and the Spatial Light Modulator's Driver Electronics for Miniaturized Holographic 3D Imaging
… this thesis is to develop a low-cost, high power laser diode/fiber illumination system and to design the driver electronics of the spatial light modulator (SLM) for holographic, three dimensional (3D) imaging. A miniaturized laser diode/fiber/polarizing illumination system capable of 15mW of …

Operational characteristics and grating tuning of quantum well heterostructure lasers
… 1-x}$As quantum well heterostructure diode lasers showing that the large band filling range of a combined GaAs-In$\sb{\rm x}$Ga$\sb{\rm 1-x}$As quantum well makes possible a very large tuning range in external grating cavity operation. The bandfilling and gain profile are shown to be …

Novel solid state modulator for the infrared: the germanium chopper
… suitably prepared germanium by excitation from a diode laser source. The process utilises inter valence band transitions from the light-hole to heavy-hole band, requiring excitation power densities in the order of Watts cm<sup>-2</sup>. This has been exploited by the construction of the first …
