If you are applying to a PhD, don't use an LLM in composing your proposal. If you are doing a PhD, don't use an LLM to do the writing and reading and thinking for you. Sorry, I am going to die on this hill.

Visit my group's post-deadline talk at CLEO/Europe-EQEC to find out what's been consuming an enormous amount of our time, energy and money(!) lately. Nikoleta Kotsina will present TW-scale optical attosecond pulses and sub-3 fs DUV pulses with more than 170 µJ of energy!! 🧪💡⚛️😎

Congratulations to @nickkarpowicz.bsky.social and co-authors! This is a major contribution to our field. I am still digesting the details, but this is a wonderful piece of work!

🎉New paper! doi.org/10.1364/OE.5... 📝 We look at how different numbers of capillaries affect the guidance properties of hollow core fibres, enabling the guidance of ~ 50 modes in the near-infrared. Some cool fibres in here that guide the visible and ultraviolet #science #optics #photonics

If you burn down a forest, you don't miss out on lumber for just that season. You have to replant all the trees, nurture them, and wait for them to grow. The science and research budget cuts happening now are wanton, senseless arson. Recovery, if it ever happens, will take generations.

Why are my lasers so expensive?

Our optica paper, "Tunable megawatt-scale sub-20 fs visible pulses from a fiber laser source", is out! Happy to have been a part of this during my time at Heriot-Watt opg.optica.org/optica/fullt...

Announcing a PhD position starting October 2025, on Applications of Machine Learning in Ultrafast Nonlinear Fibre Optics. The advertisement will be out soon, but my email is easy to find, so please send me a CV if interested. Experience in experimental & numerical photonics highly desirable!

Even accepting the premise that AI produces useful writing (which no one should), using AI in education is like using a forklift at the gym. The weights do not actually need to be moved from place to place. That is not the work. The work is what happens within you.

The @uniofbath.bsky.social Optical Fibres group is hiring! They are looking for a Professor and two Lecturers to join. If bespoke optical fibres could benefit your research, this is an opportunity. More info: www.bath.ac.uk/research-gro...

A Brief History of Kids Today Have Too Much Freedom 🧵

Traditional multi-mode #optical fibres are straightforward, but the same is difficult to achieve in hollow core fibres. We report anti-resonant hollow core optical fibres guiding at least 50 spatial modes in the infrared (~5-fold improvement ). #science #photonics #research arxiv.org/abs/2501.12996

An embarrassment of riches

Our recent paper in @opticapubsgroup.bsky.social Optics Letters presents the first relativistic plasma-mirror high harmonic generation on a liquid-sheet target. This is a real game changer for plasma mirrors ! Persistent kHz-rep.-rate with unprecedented stability. doi.org/10.1364/OL.5...

Scientist types as #DnD classes: Fighter: The best way to approach any problem is to do an experiment first and ask questions later (assuming there is any question left to ask). Very high volume of fire, but needs a constant stream of money to pay for fancier and fancier equipment. 1/

Hello @bsky.app from the #JuliaLang community! We're excited to start posting here on Bluesky in addition to our other social media, all of which can be found here: julialang.org We'll keep you updated on our fantastic community, our conferences, #JuliaLang updates, and more on this profile!

Bonnie Scotland 🏴󠁧󠁢󠁳󠁣󠁴󠁿

Hi all! Lots of new activity here, so I will introduce myself! I'm a UK early career researcher in photonics. I 🔹 Fabricate novel optical fibres 🔹 Post-process them to create advanced devices 💡 Focused on UV hollow-core fibres & applications in healthcare. I use bsky to post about my research 🔬

My fist computer was the ZX Spectrum. Great memories - I can steel feel the soft rubbery keys!

🧵SALT🧵 It's been snowing in the UK and the road gritters are out in force, begging the question: Have you ever wondered where that grit actually COMES from? The answer is more magical, beautiful and fascinating than you probably realised. 1/14

Reader, I do not know the demons that haunt your dreams, the frustrations and insults of life that have brought you to your knees, the sadness you battle in your heart. But know this: there is pure goodness in this world. It exists. Sometime we see a glimpse of it. Today, I got such a peek.

I’m going to post “Code is Just” here the same way as I did originally on Twitter, one day at a time, starting tomorrow. If you read and loved the original, as I know so many of you did, I’d feel grateful if you’d talk about it in your own words, though don’t feel obliged of course. 🧵👇🏽tomorrow

I’m really looking forward to the attosecond physics session this morning at the IEEE Photonics Conference (IPC) in Rome. 💡
