This project will create new pulsed mid-infrared fibre lasers based on original and recently developed passive switching techniques. An original class of fibre laser systems will be shown that is based on the internal placement of saturable absorbers within the optical fibre itself. A configuration such as this will enable the production of very simple pulsed laser systems of high efficiency and potentially high power. This will lead into the development of practical pulsed oscillator systems the output of which can be used directly or optically amplified for applications requiring high power.Read moreRead less

This fundamental change in our understanding of light properties generated a frenzy of scientific interest and we now have a basic understanding of the physical processes involved in slowing light. What we do not have, however, is a method of doing so that can be harnessed into useful applications outside of the lab. Our proposed approach offers a low power solution that can be readily incorporated into a myriad of engineered devices.Read moreRead less
