Research on X-ray and gamma-ray beams highlights their advantages in interstellar communication, offering new strategies for ...

Researchers have developed a new method for flexibly creating various needle-shaped laser beams. These long, narrow beams can be used to improve optical coherence tomography (OCT), a noninvasive and ...

The gem 561 laser from Laser Quantum provides up to 1000 mW of yellow light in a near diffraction-limited TEM00 beam with an M²<1.2. The gem 561 can be easily integrated into OEM applications and has ...

If you shine a beam of light from a laser or flashlight, the beam will spread out over distance, becoming wider and less intense far from the source. That phenomenon is called diffraction, and it is ...

Optical computing could benefit from the recent development of a novel electromagnetic wave. An unusual wave that does not spread out as it travels could become a key component in speedy computer ...

(Nanowerk News) Using spiraling x-ray beams generated at the Advanced Light Source (ALS), researchers differentiated between energetically equivalent (“degenerate”) states in an antiferromagnetic ...

The unfulfilled desire of crystallographers to measure the phase of diffracted beams produced by X–ray diffraction tools is actually rather pointless, according to Emil Wolf, a theoretical physicist ...

As we all know, light on its own tends to travel in a straight line. When it gets sent through an aperture like a flashlight, diffraction occurs, which causes the beam to widen and lose its intensity.
