But a half century in the past Townes and Schawlow were not basically positive what might be accomplished with their creation—or with its prototype, the maser (which utilised microwaves instead of seen light). They just knew they'd discovered a nifty way to make light shine solid and straight.
a selected light or illumination by which an object viewed usually takes on a specific visual appeal: viewing the portrait in dim light.
utilizing or making use of small or slight force or power: The kid petted the puppy with light, Mild strokes.
It is really well worth noting that our eyes are built to detect the kind of light that is radiated in abundance by The actual star—the Sunlight—that offers lifetime to our World.
