Summary of the impact

Research at the University of Manchester on laser cleaning of Ti alloys has resulted in practical implementation of the technology at Rolls-Royce for the automatic preparation of surfaces prior to electron beam welding. This has been applied to 24 different aero-engine component types including compressor drums across most current engine families. This has resulted in close to 100% `first time right' aero-engine component welds. The technology is also being adopted by BAE Systems to replace chemical cleaning during airframe manufacture. The elimination of manual and chemical cleaning processes results in savings of several million pounds per annum.

Summary of the impact

This is an example of early economic impact where research on various aspects of laser engineering has resulted in the development of inexpensive, compact, efficient and user-friendly laser sources. An example is the incorporation of quantum dot structures into semiconductor laser architectures, with these replacing much larger and more expensive systems, with a range of applications in areas such as microscopy, biomedical diagnosis and therapy. This work has led to the generation of key know-how and patents that have been subsequently licensed as well as resulting in a variety of laser-related products being brought to market. Additionally, it has resulted in extra staff being employed at one of our partner companies.

Summary of the impact

Research in solid state lasers and non-linear optics in the Department of Physics has led to the creation of innovative laser companies in Glasgow serving global scientific and industrial markets. World-leading products have opened up applications in biomedical imaging, security, defence, pollution monitoring, material processing and fundamental spectroscopy. The companies Coherent Scotland Ltd and M Squared Lasers Ltd can trace a direct link to the research in the Department of Physics and are the central theme of this case study. Since 2008, these two companies have created an estimated 600 person years of employment and £135M of sales from products underpinned by research undertaken at Strathclyde. The wider cluster of companies, researching, designing and developing laser products, including Thales Optronics and more recently the Fraunhofer Centre for Applied Photonics, which has a close working relationship with the University, has made Glasgow one of the leading European centres for innovative laser manufacture.

Summary of the impact

Impact: Economic gains / altered business practices.

Research on ultrafast lasers has led to the development of new products and services and has been pivotal in the development of a whole field of new technology.

Significance: The research underpins the product development of a range of world leading companies including Femtolasers, Newport Spectra-Physics and Menlo Systems.

Reach: The companies that use the technology represent all of the leading players in the solid-state femtosecond laser field, a marketplace worth more than $250M annually.

Beneficiaries: The impact presents economic gains to the companies involved and underlies many applications in e.g. biology and medicine, providing significant benefits to the public at large.

Attribution: The research was performed by Professor Sibbett's group.

Summary of the impact

Pound-Drever-Hall (PDH) locking, developed into a practical technique by researchers at the University of Glasgow, is the ubiquitous method for the precise frequency control of stable laser systems. This control is central to laser products from companies such as Toptica and Newport, and has an estimated global annual market in excess of £5M. The PDH stabilisation technique is essential for the operation of the time standards maintained in all of the world's Governmental Metrological Standards Laboratories (e.g. NPL, NIST, BIPM) and finds applications in inspection tools in the semiconductor industry and deep UV lasers for UV-Raman spectroscopy.

Summary of the impact

The development by Tallents et al of a new plasma opacity measurement technique contributed to the decision by the UK Ministry of Defence (MoD) to construct the £150 million Orion laser at the Atomic Weapons Laboratory (AWE) for the measurement of material properties at high energy density. Orion will enable AWE to measure e.g. opacities important in nuclear weapons design without underground tests and at much lower cost than would have been the case if it had followed the French and US programmes with lasers costing over £1 billion.

Summary of the impact

Midaz Lasers Ltd is a spin-out laser company formed by academic founders, Professor Michael Damzen (Director and Chief Technology Officer, CTO) and Dr Ara Minassian (Chief Scientific Officer, CSO), in 2006 as the vehicle for commercial exploitation of patented laser technology [4] arising from Prof Damzen's research group in the Physics Department at Imperial College London.

Midaz has designed and assembled multiple engineered laser and amplifier products, incorporating this patented technology, and has sold units to industrial customers in Europe, N. America and Asia since 2010. The primary market and beneficiary for Midaz laser technology is the industrial laser manufacturing sector and the benefit of the technology is to create laser industrial tools for higher throughput and lower cost manufacturing, including in the semiconductor industry for production of consumer electronics. In July 2012, Midaz was successfully sold to world-leading laser company, Coherent Lasers Ltd, for $3.8 Million.

Summary of the impact

A range of techniques based on laser physics and developed since 1993 by the group of Prof Telle in our analytical laser spectroscopy unit (ALSU) has led to:

• Founding a spin-off company, Applied Photonics which produces remote-sensing products employing laser spectroscopy to detect the chemical composition of unknown samples aimed at the military and nuclear energy industry. This technology has allowed multi-million pound savings on the operational costs of nuclear plants due to their functionality in normally inaccessible radioactive environments thus avoiding the need for a power station shutdown.
• Establishing a laboratory in the Atomic Weapons Establishment (AWE) dedicated to the stewardship of UK's nuclear weapons stockpile and chemical explosives by detecting isotopic abundances in uranium samples and analysing the composition of munitions deteriorating in desert environments;
• Assisting the design and development of a new product line of Spectrum Technologies, a market-leading company which removes specialised enamel insulation from conductors used in the aerospace industry.
