New research out of MIT could lead to smarter airport scanners able to detect the presence of drugs and explosives. At the heart of the development is a new approach to laser tuning designed to ...

Aug. 22—TUPELO — Born in South Dakota and raised in Tupelo, Kimberly Schipke has traveled the world to hone her skills and to share her knowledge of alternative medicine. As founder of Biofield Lab, ...

It sounds like something more suited to an android than a human being: Tuning our central processing center (that would be our brain) by using pulses of light or sound to get rid of distress. But that ...

Engineers have developed the first practical method for tuning terahertz quantum cascade lasers. What's more, the method is a fundamentally new approach to laser tuning that could have implications ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.210013 overviews a new approach to tuning the optical third-order nonlinearity of boron nitride. Hexagonal boron nitride (h-BN) is ...

Metasurface holograms (meta-holograms) are ultra-thin artificial surfaces designed to shape incident light and project it to extremely wide angles. Meta-holograms have opened up numerous possibilities ...

The Hedgehog Mid-IR Laser from DRS Daylight is a next-generation tunable laser head that is perfect for OEM or laboratory applications. Developed using advanced External Cavity Quantum Cascade Laser ™ ...

A new laser can produce infrared beams over an unprecedented range of wavelengths. A laser developed at Agency for Science, Technology and Research (A*STAR), Singapore, can produce infrared beams over ...

Laser tuning gratings are holographic gratings specially designed for wavelength tuning of lasers, such as dye lasers, Ti-sapphire, or external cavity diode lasers. The groove depth is optimised to ...

This article describes an overview of recent developments in fabrication and uses of self-assembled photonic crystals (PCs) of organic and polymer materials, such as chiral liquid crystals (CLCs) and ...
