Researchers have managed to 'pluck' a single photon, one particle of light, out of a pulse of light.  The researchers set out to demonstrate a scheme for pulling just one photon out of a stream…

Since their first use in the 1960s, there has been a tremendous expansion of laser technology into an impressively wide range of uses, from fundamental science, health care and security to…

In several years - in perhaps decades, or maybe never - our computers, nanoantennas and other kinds of equipment could operate on the base of photons, rather than electrons. Even now we are…

The Institute of Laser Engineering (ILE), Osaka University, has succeeded to reinforce the Petawatt [3] laser "LFEX" to deliver up to 2,000 trillion watts in the duration of one trillionth of one…

By Rebecca Boyle, Inside Science -- When light bulbs colonize our homes, humans get much less sleep. It's an intuitive idea, but a new study measures this effect in a real-life situation for the…

Scientists have developed the first liquid nanoscale laser and it's tunable in real time, meaning you can quickly and simply produce different colors, a unique and useful feature. The laser…

In a recent study, scientists have presented a new technique that significantly reduces the halo effect that is generated when using multi-focal. contact and intra-ocular, lenses and looking at…

Light is a useful tool for quantum communication, but it has one major disadvantage - it travels at the speed of light and sometimes things need to be kept in place, or at least slowed down. Like…

 Most people don't realize that light can take different shapes. In the fundamental mode, light energy is most intense at the center and gradually fades towards the edge of the beam. Light also…

Modern life and inadequate exposure to natural light during the day combined with overexposure to artificial light at night is believed by some to be harmful to the body's natural sleep/wake cycle.…
