But what is a laser? How is laser light different from regular light? ... With laser light all the crests and troughs line up with each other. ... That is exactly what makes laser light special. It is very organized waves with all the light exactly the same color and going in exactly the same direction. We can also think of...

An optical transistor that uses one laser beam to control another could form the heart of a future generation of ultrafast light-based computers ... But when the molecule is also targeted with a green laser beam, it starts to produce strong orange light of its own and so boosts the power of the orange output beam.
