This thesis focuses on the production of gallium lanthanum sulphide (GLS) microspheres and their potential uses. Microspheres, and micro-resonators in general, have attracted considerable attention because of their promise in all-optical-switching, micro-lasers, multiplexers and many other applications. In this thesis, several applications have been investigated, culminating in the demonstration of laser action in a neodymium doped GLS microsphere. The possibility of using microspheres as ball lenses has been investigated and shown to be possible. Laser action was observed in a neodymium doped GLS microsphere. The laser had a threshold of 83mW of incident pump power, with a peak at 1082nm and a line width of <0.05nm
