Title : Novel Designs and Applications of Mode-Locked Lasers
Abstract
The mode-locking of lasers provides a direct route to high-power femtosecond optical pulses having many applications in research and industry. There is thus considerable interest in finding new methods of mode-locking as well as understanding the basic mechanisms behind the pulsing characteristics of such devices. In this talk, I will describe our latest work in this area focusing on three main areas. The first is a new design for passively mode-locked fibre lasers operating in the all-normal dispersion regime. The second looks at how we can model such lasers using both traditional and new approaches. Finally, I will discuss some applications of mode-locked lasers including monitoring the alpine fault for geophysical activity. This work takes place within the Dodd-Walls Centre for Photonic and Quantum Technologies, which is a NZ government funded centre of research excellence. We have activities spanning a wide range of research from the properties of cold matter and Bose-Einstein condensates to micro-resonators for optical frequency combs and fundamental investigations into the basics of quantum optics. I will also briefly introduce the Dodd-Walls Centre and discuss possible areas of research collaboration.
