Acetylene-filled fiber laser produces 3.1µm-3.2µm wavelengths, long-sought by photonics R&D groups. Two different forms of hollow fiber used in mid-IR laser experiments. Researchers at Bath University ...

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 ...

Researchers have conducted the first field tests for a new laser-based system that could one day be used to continuously monitor for costly and dangerous methane leaks at oil and gas production sites.

An excimer laser's high-power ultraviolet emission enables applications in research, micromanufacturing and biomedicine. Rainer Paetzel and Ruediger Hack provide an introduction to the technology and ...

A revolutionary new type of laser is promising major advances in remote sensing of greenhouse gases. The new work has shown that the new laser can operate over a large range within the infrared light ...
