Mathematical optics

In the mathematical optics research group, led by Dr Andrew Forbes, studies are directed at the various aspects of modern optics, including laser beam shaping, laser beam propagation and novel resonators. Both the mathematical basis of these fields, as well as applications of this research in such diverse areas as optical tweezing in bio-photonics, high-energy laser delivery through a turbulence atmosphere, vortex beams carrying angular momentum for quantum entanglement and novel laser resonators for high-brightness lasers, are investigated. This research builds competency in mathematical algorithms applied in optics - both theoretically and computationally - novel laser resonators, non-linear optics, diffractive optical elements, micro optics, adaptive optics, refractive beam shapers, digital holograms, spatial light modulators and wavefront sensing.

The group communicates its results through publications and poster presentations, and has a strong student group working towards MSc and PhD degrees, as well as several collaborative partners both nationally and internationally.

We welcome interest from new partners with an interest to collaborate, and have MSc studies, PhD studies and vacation work opportunities for good students.

Research themes include:

  • Optical turbulence
  • Novel laser resonators
  • Digital holography
  • Optical vortices and vortex beams
  • Optical trapping and tweezing
