Quantum cascade lasers (QCLs) exhibit extreme pulses

Extreme events occur in many observable contexts. Nature is a prolific source: rogue water waves surging high above the swell, monsoon rains, wildfire, etc. From climate science to optics, physicists have classified the characteristics ...

New microchip devices produce a wide range of laser hues

Researchers at the National Institute of Standards and Technology (NIST) and the University of Maryland have developed a microchip technology that can convert invisible near-infrared laser light into any one of a panoply ...

Researchers fabricate high-quality transparent ceramic

Mid-infrared lasers have been widely used in imaging, detection, diagnostics, environmental monitoring, medicine, industry, defense and others. For mid-infrared laser systems, low phonon energy gain materials are key factors.

On-chip light source produces versatile range of wavelengths

Researchers have designed a new chip-integrated light source that can transform infrared wavelengths into visible wavelengths, which have been difficult to produce with technology based on silicon chips. This flexible approach ...
