NASA's Webb Telescope to witness galactic infancy

Scientists will use NASA's James Webb Space Telescope to study sections of the sky previously observed by NASA's Great Observatories, including the Hubble Space Telescope and the Spitzer Space Telescope, to understand the ...

Extending VCSEL wavelength coverage to the mid-infrared

Vertical-cavity surface-emitting lasers (VCSELs) are small, semiconductor-based lasers that emit optical beams from their top surface, and one of their main applications is in gas sensing. Gases each have a unique set of ...

New laser to shine light on remote sensing

A revolutionary new type of laser developed by the University of Adelaide is promising major advances in remote sensing of greenhouse gases.

A sense for infrared light

Laser physicists from the Max Planck Institute of Quantum Optics developed a measuring system for light waves in the near-infrared range.
