The research programme combine the inter-related activities of laser spectroscopy and material development in laser gain and nonlinear media. Linear and non-linear optical spectroscopy of Lanthanide and Transition-metal ions in insulating host remains the back bone of the research activities, in particular two-photon fluorescence, energy transfer processes and order/disorder structures. Particular areas of interest include the static and dynamic properties of transition-metal and lanthanide ions in low phonon hosts and the applications of linear/non-linear properties of optical materials in guided-wave geometry and nano-crystallites. Dynamic features dealing with interline and intraline energy transfer processes arising from ion-ion interactions, electron-phonon and phonon-phonon interactions can now be probed directly giving a better understanding of the relaxation processes, pumping cycle and phonon dynamics in laser gain hosts and other optically active materials. The research areas of energy transfer and energy upconversion lead logically to fluorescence cooling which has potential applications in the optoelectronic industry and bio-labelling/imaging in biomedical when applied to nano size crystallites. Research activities in recent years have developed into new areas and have expanded from fundamental research to more application oriented research, primarily based on applications of spectroscopic techniques and exploiting the unique properties of the optical materials.
