Meetings
WCUS attends the Central Laser Facility User meeting
James and Jack attended the Central laser facility users meeting to learn about the projects that they have been working on in the last year. Some of our own work featured also as Junn presented his research into diamond defects. Junn's WCUS measurements have been augmented with some 2D-IR results taken at the Ultra Facility.
Thanks for attending the UK THz Workshop
Thanks to everyone who attended the UK THz Workshop last week! We had a packed schedule of talks, over 30 posters, and 100 attendees from across the UK and beyond. Many congratulations to our Poster competition prize winners:
Congratulations to our poster prize winners: Reshma Anamari Mohandas (Leeds) and Peter Karlsen (Exeter) won the postdoc prize; Luana Olivieri (Sussex), Connor Mosley (Warwick), Lucy Hale (UCL) and Matt Reeves (Bath) won the PhD prize.
Nobel Prize Colloquium : Intense Laser Beams
On 24th October a special Departmental Colloquium in the Physics Department commemorated the recent 2018 Nobel Prize in Physics awarded to Arthur Ashkin, Gerard Mourou and Donna Sutherland. The prize celebrated the trios' "groundbreaking inventions in the field of laser physics”. Dr Gavin Morley spoke about the invention of optical tweezers, and their widespread adoption and use today. Dr James Lloyd-Hughes described the discovery and principles of chirped-pulse amplification, which is now used worldwide to create incredibly intense laser pulses for laser machining (micromachining and laser eye surgery) and scientific applications.
Chirped pulse amplification is the technique used in WCUS to produce our amplified laser pulses, which we use to perform ultrafast spectroscopy across the electromagnetic spectrum. As an example of the extreme intensity now routinely available, this video shows the focussed laser beam output producing a plasma (white ball, bottom right). The "buzz" on the video is the sound of the laser creating a mini explosion 1000 times per second. In addition to glowing, the plasma acts as a non-linear source of light, hence the blue/white/red glow on the top left. Thanks to Dr Mick Staniforth & Connor Mosley for the video.
UK-THz Workshop @ Warwick
We would like to invite you to the University of Warwick in December to a workshop on terahertz (THz) science and technology, with the theme "THz Instrumentation and Applications". The scientific and technical session of talks and posters will be on Tuesday 11th December, with a welcome dinner on campus the night before (Monday 10th). The event is being organised by Emma MacPherson & James Lloyd-Hughes in Warwick, with help from some of the previous EPSRC Teranet network steering group. Registration and the programme are available here.
Conference presentations
WCUS members have been presenting our recent work at a few conferences so far this year.
Connor Mosley will be talking at this year's APS March Meeting in Los Angeles about our recent work on hysteresis and spin disorder in the magnetically-induced multiferroic CuO.
James Lloyd-Hughes gave an invited talk at the Max Planck Society's "Functional Interfaces in Materials and Chemistry" research school's annual workshop in Schloss Ringberg, Bavaria. This was an excellent meeting - thanks to the organisers!
James also gave an invited talk at the 2nd Terahertz and Materials Meeting at the University of Chester - thanks to Dr Bin Yang for the invitation and the exciting day of talks.
