This report details the work cared out at Heriot-Watt University over the last three years on the project titled Mid-infrared photonic devices fabricated by ultrafast laser inscription grant award number FA8655-13-1-3026. This research was done in very close collaboration with the Novel Laser Technologies group at Sensors Directorate AFRLRYDH at WPAFB in the USA. This project follows on from an initial grant thatl ead to the developed of the first ZnSe waveguides. In this report will detail our development of CrZnSe waveguide laser in which we have demonstrated continuous wave, Modelocked and wavelength tuneable laser operation. Moving on from our work in CrZnSe we started developing waveguides in FeZnSe and have demonstrated the first FeZnSe waveguide laser. Once the base laser sources had been developed the project moved on to the developed of waveguide component to facilitate the creation of a wavelength tuneable Mid-IR laser with no free space optical elements. To achieve this waveguides fabricated using ultrafast laser inscription in CaF2 and SBN have been developed at Heriot-Watt University.
