“Light Under Flawless Tutelage Knows No Limits:” Sixty Years Of Lasers Finding New Problems To Solve
This Saturday, May 16, is the 60th anniversary of the first working laser, achieved by Theodore Maiman at Hughes Labs in 1960. At the time, one of Maiman’s colleagues, Irnee d’Haenens, famously dubbed the laser “a solution in search of a problem”—it wasn’t immediately obvious what a coherent source of light was really for.

The Laser at 60
Six decades after the first working laser was demonstrated, OPN offers a few samples of the incredibly rich field the device has created. The business end of Maiman’s 1960 laser could be held in the palm of one’s hands. That’s a far cry from the enormous, football-field-scale terawatt and petawatt laser complexes of the U.S. National Ignition Facility and Europe’s Extreme Light Infrastructure, and the 100-PW Station of Extreme Light being built in China.

The Densest Object On Earth — Made By Lasers
There are places in space where truly extreme pressures exist. But normally you find them in unpleasant locations like the centers of planets where we do not usually visit.
