Generation of mid-infrared supercontinuum (see submitted ATTRACT proposal “SMIL”) requires the development of a sub-ns laser source based on thulium-doped silica fibres. In order to achieve sub-ns pulses, a novel semiconductor saturable absorber (SESAM) will be developed within this project. Unlike off-the-shelf SESAMs from a commercial supplier, the consortium will develop a custom GaSb-based saturable...
