Laser beams can be used to precisely measure an object's position or velocity. Normally, a clear, unobstructed view of this object is required. Irregular environments scatter the light beam - but ...

A beam of light from a laser, however, does not spread and diffuse because the photons have the same frequency and phase and is thus called coherent light. In the team's research, ...

xLight, a US startup aiming to commercialize particle accelerator driven free electron lasers (FELs) for use in semiconductor production, says it has raised $40 million in a series B round of venture ...

On target: profile of the electron beam at the Advanced Light Source. (Courtesy: Berkeley Lab) Machine learning has been used by scientists in the US to reduce unwanted fluctuations in photon beams ...

One needs coherent light for a start, and it generally only gets touchier from there. But now researchers describe a new kind of holographic camera that can capture a scene better and faster than ...
