Coherent laser ranging systems confront a fundamental trade-off: higher resolution typically comes with increased system complexity and cost. Researchers from Tsinghua University have demonstrated a ...

Some of the X-ray radiation circulating in the cavity is allowed to escape downstream, providing a beam of monochromatic and coherent X-ray pulses. They have called their system X-ray Free-Electron ...

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 ...

For the first time, researchers have shown that 3D-printed polymer-based micro-optics can withstand the heat and power levels that occur inside a laser. The advance enables inexpensive compact and ...

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 ...

Scientists have successfully miniaturized a powerful erbium-based biber laser on a silicon-nitride photonic chip. Since typical erbium-based fiber lasers are large and difficult to scale down, the ...

Fiber lasers use an optical fiber doped with rare-earth elements (erbium, ytterbium, neodymium, etc.) as their optical gain source. They emit high-quality beams, they are efficient and durable, and ...

Add Yahoo as a preferred source to see more of our stories on Google. Chinese scientists have developed a portable 2-kilowatt (kW) fiber laser weapon that can operate in extreme temperatures.

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 ...

Laser cleaning systems are increasingly being used by composites part manufacturers to clean production molds, offering increased efficiency and reduced cost while also improving the environmental ...
