3D laser beam shaping


Project Description

Combining 2D beam shaping elements (including refractive and diffractive elements) with bespoke focussing optics to shape a laser beam though the entire focal volume rather than in a single focal plane.

Lasers are often valued for their ability to deliver energy into a material. This is most obviously the case for laser based manufacturing but is no less true in a range of laser-material applications including optical sensing, non-linear physics, and medicine. The use of 2D beam shaping optics has taken off in recent years. This allows a bespoke energy distribution on the surface of a material; something more optimised for the application. 2D beam shaping, however, is limited in that it only works at or very near to the focus of the laser beam. For non-linear based processes or those where the correct focal plane is not well defined (e.g. surgery) this presents a problem.
3D beam shaping would solve this issue. By tailoring the energy distribution over the whole focal volume it will be possible to significantly simplify and improve a whole range of laser processes.

Requirements
All applicants must have or expect to have a 1st class MChem, MPhys, MSci, MEng or equivalent degree or be on track for an award before start of project (nominally October 2020). Selection will be based on academic excellence and research potential, and all short-listed applicants will be interviewed (in person or by Skype). DTP funding is only open to UK/EU applicants.

Funding Notes

The annual stipend will be approx. £14,777 and full fees will be paid, for 3.5 years.
