In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...

Components of a typical laser include gain medium, laser pumping energy and resonant optical cavity. The output frequency of most lasers is fixed or within a small range, and it is difficult to ...

According to SPIE, researchers from the Chinese Academy of Sciences (CAS) have created a "breakthrough" solid-state deep ultraviolet (DUV) laser emitting coherent 193-nm light used for semiconductor ...

Engineering researchers report that they developed a new, efficient way to modulate and enhance an important type of nonlinear optical process: optical second harmonic generation -- where two input ...

Teradyne Inc.’s assembly test division today introduced an optical process test (OPT) system for post-placement, inline defect detection and process measurement. The company said the non-contact ...

A team of researchers recently developed an alternative way to break the Abbe diffraction limit and realize subwavelength imaging in an all-optical manner. They propose localized evanescent-wave ...

A code sleuth has found new details about how Apple Vision Pro Optical Inserts will need to be set up and paired, and the process is a little involved. Apple Vision Pro is a tight fit, so users will ...
