Holograms are three-dimensional (3D) images produced by interfering beams of light that reflect physical objects or photographs. In recent years, they were introduced in a variety of settings, for instance to enhance employee ...
Physicists at JILA have demonstrated a novel "superradiant" laser design, which has the potential to be 100 to 1,000 times more stable than the best conventional visible lasers. This type of laser could boost the performance ...

(Phys.org) —Researchers working at Japan's NTT Basic Research Laboratories have successfully built an all mechanical phonon laser. In their paper published in Physical Review Letters, the team describes how they built a ...
(PhysOrg.com) -- One of the issues associated with lasers is their tunability. In many cases, if you want to produce a particular wavelength, you have to build a laser to accomplish this. In order to get another wavelength, ...
Researchers in Japan have turned to mathematics to build a computerized 3D model of the female trunk that could help lingerie and other clothes designers make more sensuous, comfortable, and better fitting product ranges.
