Scientists get peacock feathers to emit laser light after adding dye and green pulses, revealing surprising biophotonic ...

A project at Swiss research center EPFL has manufactured a palm-sized all-glass GHz femtosecond laser cavity, potentially offering a novel route to free-space femtosecond lasers. Conventional ...

When researchers at the Galatea laboratory in Switzerland set out to create a femtosecond laser in glass they weren’t certain it was going to work. To be precise, their goal was to create a ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.240077 , discusses agile cavity ringdown spectroscopy enabled by moderate optical feedback to a quantum cascade laser. Optical ...

More than 200 years ago, Count Rumford showed that heat isn’t a mysterious substance but something you can generate endlessly ...

External cavity laser diodes (ECLs) are lasers with a very small line width, excellent wavelength stability, and very low noise. They are used in optical communication and fibre sensor technology.

An international research team uses topological platform to demonstrate coherent array of vertical lasers. Israeli and German researchers have developed a way to force an array of vertical cavity ...

Important instruments for neuroscience and medical diagnostics, optically pumped magnetometers measure responses of polarized atoms to produce information about the low-frequency external field. They ...

The devices and tools used in medicine are becoming smaller. They have greater functionality and are expected to last longer than earlier devices. Design, manufacturing, and packaging the devices and ...

Peacock feathers are greatly admired for their bright iridescent colors, but it turns out they can also emit laser light when dyed multiple times, according to a paper published in the journal ...
