High-precision optics are essential for commercial laser-driven fusion

1 week ago | laserfocusworld.com | Sally Johnson

Beyond laser technology advances, the path to putting commercial laser-driven fusion energy on the grid by the 2040s or 2050s requires high-precision optics that can meet stringent optical, mechanical, and thermal specifications to withstand extreme conditions. Laser-driven fusion technology is currently being fast-tracked to put carbon-free energy on the power grids—and hopefully help save the planet.
PODCAST: Interview with Siddharth Ramachandran, Boston University

1 week ago | laserfocusworld.com | Justine Murphy

This episode features Siddharth Ramachandran, a distinguished professor of engineering at Boston University. He started his career in industrial research at Bell Labs, and his work with light-wave devices has helped advance optical networks, laser-based defense systems, brain imaging, and quantum computing. Here, he talks with host Justine Murphy about his experiences in the industry, from research to academia and beyond.
FYLA grows to meet industry’s ultrafast laser needs

1 week ago | laserfocusworld.com | José Pozo

As a child, Pere Perez-Millan loved nature—especially astronomy—and wanted to understand the world from a scientific point of view. It led him to an undergraduate degree and Ph.D. in physics from the University of Valencia and the creation of FYLA, a company that specializes in ultrafast lasers and systems for scientific and industrial applications. It’s no surprise that nature still plays a role in Perez-Millan’s outlook, the philosophy of his company, and his lasers’ practical applications.

Tyler brings a global perspective and years of experience to his work bridging the realms of technology and business, and is dedicated to inspiring the next generation.
Quantum ‘tornadoes’ experimentally shown within momentum space

4 weeks ago | laserfocusworld.com | Sally Johnson

A quantum “tornado” is a simplified term for an orbital vortex line, and work led by Maximilian Ünzelmann, a Complexity and Topology in Quantum Matter (ct.qmat) postdoctoral researcher at the Universities of Würzburg and Dresden in Germany, experimentally demonstrated electrons form these vortices within the momentum space of quantum semimetal tantalum arsenide (TaAs). Momentum space describes electron motion in terms of energy and direction—not a precise physical position.
Researchers demo diamond-based Raman vortex beams

1 month ago | laserfocusworld.com | Sally Johnson

Inspired by the rapid evolution and broad applications of vortex beams, an international team of researchers from China, Japan, and Australia set out to address a few challenges of traditional population inversion lasers—namely limitations in wavelength scalability and power scaling. Drawing upon their earlier work with diamond-based lasers, the researchers realized diamond’s exceptional thermo-optical properties could offer a breakthrough solution.

Topology preserves quantum information

1 month ago | laserfocusworld.com | Andrew Forbes

Entanglement, the virtual link by which information can be exchanged across vast distances, is the cornerstone of modern quantum technologies essential for communication and computing. Unfortunately, quantum entangled states are notoriously fragile and decay when they experience a perturbation. This can be as mundane as background and stray light, noisy detectors, lost photons, or defects within materials, common effects in real-world quantum systems, which render the link useless.
