Bruker Corp. says that 3D microscopy based on white-light interferometry can provide high-speed measurement with higher lateral resolution and better vertical measurement accuracy...
To this writer, this year would appear to be the winter of his discontent made glorious summer by the publication of two fascinating but difficult books. They appear to shed some...
A pulse-amplification process designed for the highest-intensity short-pulse regime looks like it could lend its power to the effort toward laser fusion.
The recent announcement from scientists at the particle accelerator at CERN that they have clocked neutrinos moving faster than the speed of light has generated considerable attention...
Ultrafast laser pulses with proper energy density and wavelength can now be used for processing materials where thermal influence must be minimized, including drilling metals ...
Welding small conductive parts is a unique challenge for welding technologies. Laser welding offers a great fit for this scale of joining; however, 1064 nm pulsed Nd:YAG technology...
An engineering team at the University of California–Los Angeles (UCLA) Henry Samueli School of Engineering and Applied Science has developed a polarizing organic photovoltaic ...
Attosecond (as) photonics is a rapidly developing tool to help scientists study the behavior of matter and energy at this extraordinarily short time scale.
The VIBE process is a full-aperture, conformal polishing process that uses high-frequency, random motion to rapidly remove sub-surface damage and eliminate mid-spatial-frequency...
Scientists from the Optoelectronics Research Centre, University of Southampton and Penn State University have created an optical fiber with a hydrogenated amorphous silicon (a...
The optical outputs of two—and potentially more—femtosecond fiber amplifiers seeded by the same oscillator can now be coherently combined, providing a way to greatly increase ...
A team of researchers from the Institute of Photonic Sciences (ICFO) and the Catalan Institute of Research and Advanced Studies (ICREA), both in Barcelona, Spain, have developed...
The development of all-optical data processing is getting a boost from European researchers who are pioneering the use of an optically active protein for ultrafast photonic switching...
A submonolayer of lead sulfide quantum dots on aluminum-doped zinc oxide forms a photo field-effect transistor; its bandgap is tunable to wavelengths suitable for use in photovoltaics...
In the nanopositioning industry, prices continue to fall as resolution, linearity, and reliability improve. Engineers can now use standard optical components and off-the-shelf...
Light can travel seemingly without diffraction in a curved arc in free space. Such peculiar optical beams are named "Airy beams" after English astronomer Sir George Biddell Airy...
Caries (commonly called cavities) in teeth can be seen more easily under near-IR (NIR) light than visible light, and in fact show higher contrast in NIR than under the blue light...
Tunable narrowband terahertz pulses in the range of 0.3 to 2.4 THz were created via difference frequency generation using a photoconductive antenna (PCA) design developed by researchers...
Advances in ultrafast lasers, beam delivery systems, and optics are helping researchers develop new applications of nonlinear microscopy and improving prospects for clinical diagnosis...
