Profile

David Spence received an MPhys degree (1997) and a DPhil (2001) from Oxford University, UK. Following two years as a Research Assistant in the Clarendon Laboratory at Oxford, he moved to Macquarie University in 2004, where he was a research fellow for two years. He now holds an ARC Research fellowship (APDF) as well as a lectureship in the Lasers and Photonics "Centre of Research Excellence".

David's research focuses on novel solid state lasers. Two main strands of reseach focus are tunable UV lasers and new mode locked laser systems. He is developing continuous-wave and mode-locked femtosecond UV sources using Ce-doped crystals that are widely tunable from 280nm to 315nm. He is also involved in the modeling of laser systems including the recently demonstrated CW Raman lasers pioneered at Macquarie University. A new research project will investigate mode locking in Raman lasers, with the aim to develop a new method of mode locking for solid-state lasers.

Research projects for Masters and PhD students are available: see here and here.
