Dr Sebastian Ng

ARC Grant-Funded Researcher A

School of Physics, Chemistry and Earth Sciences

Faculty of Sciences, Engineering and Technology

Sebastian completed concurrent degrees in BSc (Experimental and Theoretical Physics) and BE (Mechanical) at the University of Adelaide receiving first class honours in 2010.

During his degrees he worked as a Research Assistant at the Institute for Photonics and Advanced Sensing to develop rare earth doped silica fibre lasers. From 2010-2016 he completed his PhD under the Supervision of A/Prof David Ottaway and Prof Tanya Monro on a project entitled "Development of air-clad holmium-doped fibre lasers."

Since the completion of his PhD Sebastian has worked on the development of portable MidIR fibre lasers and worked as a program developer for the Graduate Certificate in Radiation Management.

He is currently working as a Research Associate in the ARC Centre of Excellence for Gravitational Wave Discovery (OZGrav) where he co-chairs the Quantum Program. His current research involves the development of high power narrow linewidth lasers for third generation gravitational wave detection, adaptive optics and alternate PNT networks.

Research Interests

Sebastian's research focuses on the application and development of laser technology. His core research interests include:

  • High power continuous wave lasers
  • Single frequency sources
  • 2 micron fibre lasers
  • Optical fibre fabrication
  • Laser stabilisation for gravitational wave astronomy
  • Adaptive optics
  • Alternate PNT
