But wait...there's more! Over #LightDay2025, we received an extraordinary response from Optica Student Chapters from around the world.
The response was so great that we couldn't include every event in one thread, so we made a page for even more! 👉

Happy #LightDay2025!
A wee bit late, but happy lasers day!
#LightDay2025
Break time is over!
With fresh perspectives from their #LightDay2025 session, the Optica students at Paderborn let us know that they're eager to inspire new students to enter the quantum field and expand the optics community at Paderborn!
#LightDay2025 is far from over.
And the International Year of Quantum is far, FAR from over - that's why the University of Bristol Optica students are celebrating how critical quantum tech and science are for sensing, metrology, communications, and more.
Can you call it a watch party without pizza?
Take a look at how the Vrije Universiteit Brussel celebrated #LightDay2025 with a party exploring the latest advancements in quantum optics!
We're not done yet!
The Multimedia University of Kenya Optica Student Chapter held engaging lectures, interactive sessions, and informal presentations highlighting key takeaways from the watch party.
How has your #LightDay2025 been?
