Graefelfing (Munich), Germany -- Cost-efficient and easy gas laser replacement with 1 Watt @ 405 nm: With the new TopWave 405 Toptica presents a cost-efficient, gas laser replacement for easy, ...

Scientists in the United States were forced to pause the development of an advanced ultrafast laser technology that could ...

Future iPhones could use laser detection of poisonous gas, air quality, or pollen. Malcolm Owen. 9. e-mail Facebook BlueSky Reddit X. Tue Sep 29 2020, 09:11 AM EDT · 3 minute read. Detecting ...

Another start-up, Xcimer Energy of Redwood City, Calif., is planning to use krypton-fluoride gas lasers, but at much higher energies — eventually, a system that puts out about twice as much ...

Laser pulses that can shred ammonia molecules dissolved in water may offer a way to generate hydrogen gas without using heat, pressure, or catalysts (J. Am. Chem. Soc. 2024, DOI: 10.1021/jacs ...

In most gas lasers, the stimulated emission action takes place within a closed optical cavity, typically formed by a glass tube whose ends are sealed with mirrors, one of which is partially silvered.

Rare gas lasers utilise noble gases such as argon, xenon and krypton to generate coherent light through the excitation of metastable atomic states. Unlike conventional semiconductor or solid-state ...

But it wasn’t until a conference in 2017 when Capasso met Henry Everitt, senior technologist with the US Army and adjunct professor at Duke University, that the idea to apply the widely tunable QCL to ...

Terahertz laser: how it works. First, a quick primer. Atoms sit at higher energy levels when excited, similar to a building’s floors. A normal gas laser holds a molecule between mirrors and ...

Gas lasers pump large amounts of energy into specific molecules such as carbon dioxide. Chemical lasers are powered by specific chemical reactions that release energy.
