Optical coating optimisation to enable the transfer of technologies from gravitational wave detection to quantum and intense light-matter experiments
Lead Research Organisation:
University of Strathclyde
Department Name: Biomedical Engineering
Abstract
Some of the most exciting experiments planned in the UK and internationally - from studying extreme light-matter interactions, to the exploitation of quantum technologies - are demanding unpreceded performance in mirror coating technology. Optical thin film coatings appear ubiquitously in the technology around us, however current available performances will not meet the requirements for, and will thus limit the exploitation from, many of these experiments. For example, emerging extreme light-matter experiments are now handling power densities an order of magnitude higher than those previously achieved. This includes major UK infrastructures, including the Central Laser Facility (CLF) and the Scottish Centre for the Application of Plasma-based Accelerators (SCAPA), in addition to partnership initiatives in Europe including the 850MEuro European funded Extreme Light Infrastructure (ELI). All these experiments will soon require laser damage threshold (LDT) performance in the highly reflective mirrors at a level not currently available. This proposal, for the first time, will seek to exploit advanced optical coating technologies, developed with the field of gravitational wave astronomy, for use in intense-light matter experiments. Moreover, the capabilities developed will significantly support existing activities within the Quantum Technologies for Fundamental Physics (QTFP) and the UK's continued effort in gravitational wave astronomy.

| Title | Establishment of the Extreme Performance Optical Coatings testbed (EPOC) within the National Manufacturing Institute Scotland (NMIS) |
| Description | This facility is the first to establish both state-of-the-art ion beam deposition (IBD) and novel modified IBD techniques to the UK photonics sector. It was established (and managed) through a partnership between the universities of Strathclyde, Glasgow and West of Scotland, alongside industrial partners Helia Photonics and Gooch and Housego. The facility gives an exploitation route for coating developments within the gravitational wave research groups, which otherwise could only be capitalised by overseas organisations. One of the UK's Quantum Technologies for Fundamental Physics (QTFP) programs (Quantum-enhanced Interferometry, led by the University of Cardiff) will be the first to exploit access to these manufacturing capabilities for the establishment of interferometric testbeds for detection dark matter and observing the potential quantisation effects of space-time. The facility also played a key role in attracting a top international applicant who was awarded an Ernest Rutherford Fellowship (Dr Mariana Fazio, ST/W004844/1). |
| Type Of Material | Improvements to research infrastructure |
| Year Produced | 2022 |
| Provided To Others? | Yes |
| Impact | Joint projects and consultation contracts are now underway with industry and we expect significant impacts to arise from this. Significant effort has also been invested by the University of Strathclyde and Helia Photonics Ltd to establish a complimentary manufacturing capability at Helia Photonics, to better support the adoption of the technology within the wider UK photonics sector. |

| Description | Nursery visits - two sessions (1 hour each) on (1) light and astronomy, and (2) our bones and artificial limbs (3 to 5 year olds, 2-3pm, 25th and 27th June 2024) - by Prof Stuart Reid and Dr Mariela Masso |

| Results and Impact | I organised and ran two interactive workshops for 3-5 year olds. The first one (25th June) explored astronomy and how we observe the stars and planets through the light the send out that reaches us. Diffraction glasses were provided to all children (around 30 each day) to show that white light is made up of all the colours of the rainbow. Understanding the colours of light that comes to us from the stars and planets is the best way for us to "touch and feel" what is in the universe - letting us know what the universe is made of, and how hot/cold it is. The second workshop looked at the bones in our bodies and how we move, and a full-scale skeleton was brought to the class to demonstrate this. We discussed how exercise and pushing on our bones helps to keep our bones healthy and strong. An artificial hand was brought in to show the children how technology can be used to help people who have missing limbs. Electrodes were attached to children's arms (each child had around 2 opportunities to try this) which allowed the children to remotely control the hand (in a stand) with their nerve signals from their arms. |

| Results and Impact | Large-scale outreach event (day) hosted by Strathclyde in connection with SmartSTEMs charity. Local schools (P6-7 and some S1, ages 10-12) were invited and over 200 children, in addition to teachers, participated. Event was arrange with keynote talk from industry (IT sector) and academia (Prof Stuart Reid, Strathclyde) followed by 3 workshops (40mins each). The talk covered quantum technologies (QTFP/QI) and gravitational wave detection. One of the workshops covered stem cell research in relation to nanokicking/bone health. Follow up events will be arranged as demand was very high - schools booked within 1 day of invitations being sent out and most applications were rejected due to demand. SmartSTEMs and Strathclyde will arrange annual or bi-annual events now. |
