Happy birthday to the laser! In the 60 years since Ted Maiman invented it, the device initially derided as "a solution looking for a problem" has become ubiquitous. Explore the laser's history and (continued) evolution with this special collection.http://ow.ly/tBk550zGn6k

Laser light could turn a normally insulating material into a conductor and vice-versa, according to calculations done by physicists @Tulane @KingsCollegeLonhttps://physicsworld.com/a/quantum-control-using-laser-light-could-turn-insulators-into-conductors-and-vice-versa/ …

Because copper only absorbs 2% of light at infrared wavelengths, it's hard to weld it with standard industrial lasers - so physicists and engineers are designing high-power blue laser diodes to fill the gap. http://ow.ly/AibK50zGm48  #Laser60

To celebrate the laser's 60th anniversary (it's Saturday, but lasers are so amazing we've started partying early), we've brought this fantastic piece on Ted Maiman and the complex early history of the laser out of our archive and made it freely available.http://ow.ly/xMHv50zGl1o
