Daylight Solutions Establishes New World Record for Broadly Tunable Solid State Mid-IR Laser

Daylight Solutions, Inc., a manufacturer of advanced molecular detection and imaging solutions, today announced that it has established a new world record for a broadly tunable solid state mid-infrared laser source in a commercial product. The company integrated a Quantum Cascade semiconductor gain chip from ALPES lasers (Switzerland) into its own patented tunable external-cavity laser (EC-QCL) system. The result was a single frequency source that tuned across 275 wavenumbers, or 24% of the laser's center wavelength at 8.8µm.

Researchers Found Way to Overcome Key Barrier to the Advent of Super-Fast Quantum Computers

MIT researchers may have found a way to overcome a key barrier to the advent of super-fast quantum computers, which could be powerful tools for applications such as code breaking. Ever since Nobel Prize-winning physicist Richard Feynman first proposed the theory of quantum computing more than two decades ago, researchers have been working to build such a device.

Specially-Prepared Light Moves Through Open Channels

Materials such as milk, paper, white paint and tissue are opaque because they scatter light, not because they absorb it. But no matter how great the scattering, light is always able to get through the material in question.
