Keller-Led Team Posts an Ultra-Short Pulse Record
Researchers at ETH Zurich have developed a laser that can produce extremely short pulses with peak powers up to 100 MW and 550 W of average power. The researchers, led by Ursula Keller, a professor at the Institute for Quantum Electronics, report that the achievement marks a record — surpassing the previous reported maximum by more than 50%. The demonstrated pulses are the strongest pulses ever created by a laser oscillator.

About Lasers and a Dinosaur
Lithuania is a small country, roughly twice the size of the State of Maryland, and with a population of 2.9 million. Its status as a photonics hotbed, especially in ultrashort pulsed laser technology, owes largely to the many reputable brands that headquarter in Vilnius, the nation’s capital city.

Fused Silica Step Index Fibers: Advanced Preform and Fiber Metrology
Tue, Dec 10, 2024 10:00 AM - 11:00 AM EST
This webinar discusses advanced preform and fiber measurement techniques for specialty fibers, with a particular focus on fibers produced using the POD (plasma outside deposition) process. In this process, fluorine-doped fused silica is applied to the outside of a high-purity core rod made of synthetic quartz glass to produce the refractive index step required for light guiding. Depending on the specific application wavelengths of these specialty fibers, various synthetic fused silica materials are available as core materials, which enable the production of specialty fiber preforms tailored to the application. The session begins with a brief introduction to the manufacturing process and typical applications of specialty fibers, followed by an in-depth examination of the characterization of the preforms and the resulting fibers. Presented by Heraeus Conamic.
