This project introduces a paradigm shift in 3.5µm mid-IR fibre lasers. A new laser process will be investigated to obtain high-power, simple and robust mid-IR fibre laser design. We will use advanced spectroscopy to characterize the fibre laser dynamics, computer modelling to optimize the laser design, and demonstrate the concept experimentally. The new design will enable agile, high precision polymer processing tailored to the unique absorption lines of carbon-hydrogen bonds in different polymers where there is currently a lack of high power, high brightness low-cost light sources. It will also open the door for very high-resolution laser assisted glass 3D-printing. The project will give Australia a new edge in advanced manufacturing.
