- Waveguide amplifiers and lasers
- Cryogenically cooled lasers for peak and average power scaling
- Ultra-fast high repetition rate compact lasers
Dr Mackenzie’s research focus is on efficient solid-state laser systems with an emphasis on the planar geometry, targeting applications whose needs range from power scaling to integration and miniaturisation. The PWSL group looks to extend the current parameter space available from solid-state laser architectures – from waveguides to cryogenically cooled gain media, through materials research and composite engineering, whilst paying particular attention to thermal management, and spectroscopic characteristics. Predominantly utilising crystalline gain media, the PWSL group is exploring exciting opportunities not achievable via standard routes, thus enabling difficult or weak laser transitions, with an emphasis on increasing the range of accessible wavelengths and demonstrating power-scalable solutions in both pulsed and CW regimes.
