Frontiers of ultrafast laser fabrication


Project Description

Ultrafast lasers offer unprecedented fabrication capabilities in terms of precision and three-dimensional flexibility. These capabilities are opening up previously impossible capabilities, such as three-dimension nano-lithography in bulk crystals [1], and the creation of unique mode-selective fibre Bragg-gratings [2]. Devices such as these have countless applications, in areas ranging from new laser technologies, to fundamental physics using the properties of quantum optics.

Recently, the photonic instrumentation group at Heriot Watt University has been awarded a substantive grant by the UK Engineering and Physical Sciences Research Council (EPSRC) to work with collaborators at UCL on the development of "Laser refrigeration on the nanoscale: From nanocryostats to quantum optomechanics,", the aim of which is to exploit controlled laser illumination of laser crystals to actually cool the material [3]. The successful applicant will thus join the multi-institution team working on this topic, and explore how the unique capabilities of ultrafast laser processing can be exploited in this area.

The successful applicant will join the photonic instrumentation group at Heriot Watt University (phi.eps.hw.ac.uk), but will work as part of a multidisciplinary and multi-institution team.

Funding Notes

This 3.5 year fully-funded studentship comes with a significant amount of ring-fenced funding for conference travel.

Eligibility: This is a Research Council funded studentship, and thus only UK students, or EU students who have been resident in the UK for 3 or more years continually, are eligible for an award of a tax-free stipend (~£15k / year) and fees.
