We just came back from our first-ever Summer Retreat.

In a world in crisis, it is ever more important to maintain a strong sense of community and mutual support.

Thanks to everyone who contributed to this fantastic weekeend and to more to come!

Congrats, Prof. Sergio Carbajo (UCLA/SLAC) on joining HPLSE’s Editorial Board!

HPLSE leads in #LaserScience, covering #PlasmaPhysics, #FusionEnergy & #ParticleAcceleration, key to next-gen tech. Carbajo’s expertise in #UltrafastOptics will drive the journal’s impact.

Our UCLA team collaborated with DESY scientists to demonstrate superradiant light sources using femtosecond/attosecond electrons.

This research advances:

More updates soon!

Meet Jesus Perez, our newest member at UCLA.

Jesus will be working on RF synchronization for laser and photonics devices, and electron beam compression techniques. He joins us with BS in Electrical Engineering from the University of Wisconsin-Madison.

Welcome to the Cooperative, Jesus!

We'll strive to demonstrate a new methodology to produce attosecond X-rays from first-principles for cost-effective and on-chip scalable X-ray photonic devices in #semiconductor, #heterogeneous integration, and #medical applications.

Thanks to a recently awarded #NSFfunded grant, we will soon embark on the next stage of one of our main lines of research in coherent #quantum #electrodynamics.

Meet Eesha Jain, our newest member at UCLA.

Eesa will be working on #quantum and #coherent transition #radiation driven by free electrons and controlled by novel QED phenomena with a Bachelor’s in Computer Engineering (Bioengineering minor) at UC Irvine.

Welcome to the Cooperative, Eesha!

“Capturing, manipulating, and emitting high-frequency waves and lights drives my passion for exploring the fundamental limits of light-matter interactions,” notes Hao, “paving the way for the next generation of photonic, biosensing, and communication technologies.”

Congratulations to our PhD candidate, Hao Zhang, for being awarded the SPIE Optics and Photonics Scholarship.

His work cuts across academic and national lab priorities by focusing on nonlinear optics, advanced pulse shaping for ultra-high-brightness light sources, and photonic transduction.

The study just published below, led by Adi Natan at SLAC and colleagues at Stanford University, Brown , and UCLA, offers a remarkable insight into the real-space and energy distribution observation of one model photodissociative process from a transition metal complex.

Additionally, controlling energy flow at the atomic level can optimize light-driven technologies, such as #photodynamic therapy, photoresponsive materials, and next-generation #optoelectronic devices.

Real-space observation of the dissociation of a transition metal complex and its concurrent energy redistribution - Nature Communications Metal carbonyl complexes show photoreactivity interesting for catalytic and biological applications. Here the authors capture the structural dynamics of the photodissociation of iron pentacarbonyl in ...

Understanding energy redistribution in #photochemical reactions is crucial in enabling the design of more efficient #photocatalysts for sustainable energy applications (e.g., solar fuels, CO₂ reduction) and precision synthesis in #pharmaceuticals.

#CLEO2025 attendees, don't miss out on the presentations by our team members this week in Long Beach, California

Our cooperative is glad to support the current and future mission of this facility and the larger scientific community, national and internationally.

It's a wrap for ATF's 27th Users Meeting. ATF staff and their users perform high impact research enabling breakthroughs in high energy physics - largely supported by DOE at Brookhaven National Lab, it's one of the flagship facilities in the country.
