2018-19: MSc Diamond Science & Technology includes the following modules:CH976 Novel and Efficient Methods of Material SynthesisPX904 Properties and Characterization of MaterialsPX905 Defects and DopantsCH977 Theory and Modelling of MaterialsPX906 Manufacturing the Future: Industrial DiamondCH978 Surfaces, Interfaces and CoatingsCH979 Devices and FabricationPX907 Diamond Photonics and Quantum DevicesCH980 Applications of High Performance MaterialsCH981 Mini Research Project 1 and 2And either CH914 or PX908:CH914 Electrochemistry and SensorsPX908 Biomedical Optics and ApplicationsProject:Lasers are a key enabling technology, powering progress from manufacturing to quantum technologies. The common thread in engineering systems tailored to these applications is to requirement to make high performance lasers smaller and more robust. Exploiting novel materials - such as high optical quality synthetic diamond - provides a route to achieving these goals. The studentship will build on the outputs of an existing of an EPSRC project on Fibre-laser Pump Diamond Raman Lasers for LIDAR and Clear Plastics Welding (EP/P00041X/1). This grant is supported by Thales Optronics Ltd, SPI Lasers Ltd, Element Six Ltd, and Fraunhofer CAP.The studentship will have two parallel themes:1. "High power Raman lasers for manufacturing and remote sensing"This theme will develop novel diamond Raman laser architectures that aim to shift the output of fibre lasers into spatial, spectral and temporal regimes where they are better suited to applications such as LIDAR and welding of transparent plastics. This work will be done in collaboration with the world-leading fibre lasers team at Southampton (Prof Johan Nilsson and colleagues) with the explicit aim of moving towards follow-on funding in the technology transfer space working with current industrial collaborators Thales and SPI Lasers.2. "Non-linear photonics of diamond colour centres"This theme will explore the laser spectroscopy, temporal and spectral dynamics of gain/induced absorption, and charge transfer mechanisms, of colour centres in diamond with relatively high concentrations (100s ppb) under high intensity laser illumination. These are the conditions required for possible laser operation, but are also potentially relevant for sensing applications.
