A random Q-switched fiber laser [PDF]

Scientific Reports, 2015
AbstractExtensive studies have been performed on random lasers in which multiple-scattering feedback is used to generate coherent emission. Q-switching and mode-locking are well-known routes for achieving high peak power output in conventional lasers.

Task Switching and Distractibility [PDF]

, 2007
In this thesis I examined the effects of task switching on people’s ability to ignore irrelevant distractors. Load theory proposes that distractor interference critically depends on the availability of executive control to minimise the effects of ...

Whispering gallery modes in semiconductor optical fibres and optical bottle microresonators

We explore the optical properties of whispering gallery modes (WGMs) in silicon optical fibres and optical bottle microresonators. In particular, a pump-probe technique is used to experimentally demonstrate thermally induced all-optical modulation.

Q-switching in fibre-lasers

, 1989
One of the most attractive features of fibre lasers is their ability to produce significant pulse powers when Q-switched. Potential applications for such lasers include non-linear switching, OTDR measurements, materials processing and range-finding.
