The paper is published in the journal Nature. In a world-first, scientists used precisely controlled optical traps, known as "magic-wavelength optical tweezers," to create a highly stable ...

The phase and the group velocity of light propagating in conventional optical media cannot exceed the speed of light in ...

Ultrasound is produced by high frequency vibrations beyond the range of human hearing. The frequency of ultrasound is therefore greater than 20,000 hertz. Ultrasound, like audible sounds ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2025.240275, discusses A highly sensitive laser gas sensor based on a four-prong ...

Scientists have developed a high-resolution distributed temperature sensing technique using plastic optical fibers, achieving a spatial resolution of 4.8 centimeters. This breakthrough, based on ...

Anybody can develop high frequency hearing loss, but it becomes more common with age. Exposure to loud sounds or high frequency sounds are common causes of ear damage in younger people.
