Personal statement

Jennifer Hastie is a Reader and Research Team Leader at the Institute of Photonics with a main interest in optically-pumped semiconductor disk lasers (SDLs, also known as VECSELs) for high spatial and spectral brightness and broad tunability at novel wavelengths. 

Jennifer recently held an EPSRC Challenging Engineering Award (EP/I022791/1) building the team’s research in the area of narrow linewidth SDLs with advanced wavelength flexibility for applications including metrology and lithography; spanning ultraviolet, visible and infrared spectral regions through the use of novel materials and intracavity nonlinear frequency conversion techniques.  A research highlight has been the development of intracavity-pumped tunable crystalline Raman lasers, including CW diamond Raman lasers, pumped within the high finesse cavities of tunable SDLs. 

As a result of the group’s work in the area of narrow linewidth SDLs, Jennifer is the Strathclyde University Lead Investigator for the UK National Quantum Technology Hub in Sensors and Metrology (www.quantumsensors.org), collaborating with Hub Director Prof Kai Bongs of the University of Birmingham to develop lasers for optical clock systems.  The Hub, which also includes leading research groups from the Universities of Glasgow, Nottingham, Southampton and Sussex, is an international centre of excellence that will translate state-of-the-art lab technology into deployable practical devices with the academics working with >60 industry partners to translate research into marketable applications.


Biography: Jennifer joined the IoP as a PhD student in 2000.  In 2004 she was awarded a 5 year research fellowship by the Royal Academy of Engineering to develop visible and ultraviolet semiconductor disk lasers for applications in biophotonics and was Principal Investigator on two further grants funded by the UK Engineering and Physical Sciences Research Council (EPSRC): for work on ultraviolet SDLs (EP/D061032/1) and on InP quantum dot SDLs (EP/E056989/1), the latter in partnership with Dr Andrey Krysa of the University of Sheffield and Prof Peter Smowton of Cardiff University.  She has also been a co-investigator on an EPSRC Engineering Platform Grant for the development of advanced solid-state laser systems (EP/E006000/1) and a grant on diamond Raman lasers (EP/E056989/1) with IoP colleague Prof Alan Kemp.

Jennifer was the Programme Chair of the VECSELs conference at SPIE Photonics West 2013 and was an active member of the Technical Programme Committee of the international OSA conference Advanced Solid-State Photonics 2009-2013. She is a Senior Member of the Optical Society of America and a Senior Member of the IEEE.

Hastie, Jennifer (Principal Investigator)
"A large number of applications, including those in research, defence, and finance require compact optical clocks that retain
their accuracy and reliability for lower costs and footprints than existing systems. Optical clocks are capable of better
stability and lower uncertainty than the current standard of time; however, each clock requires a range of lasers with
demanding requirements specific to the atomic species at the heart of the clock. Neutral strontium is one of the most
widely used atoms. It has a key transition that must be addressed using a laser source with emission wavelength at 461nm,
power 1W and linewidth (spectral purity) 32MHz. Currently researchers must use expensive or inadequate laser
sources to meet these requirements. In this project we will meet all the above requirements of neutral strontium in a low
cost, compact system based on semiconductor disk laser (SDL) technology. The advantageous properties of SDLs for
tunable, narrow linewidth operation have previously been demonstrated in the laboratory; however, their potential to
address wavelengths of interest for optical clocks, and moreover to achieve this in a compact commercial format, have yet
to be realised. We will engineer a stabilised, narrow linewidth 922nm SDL with frequency doubling to 461nm within the
cost and volume parameters required for strontium optical clock-based systems to emerge from the research laboratory
and address applications in the field."
