Laser technology celebrates 50 years

According to NPR Science Friday show which I listen to on the web.

In my childhood days of the late 60s, lasers were revered in the media for their violent power. Ability to cut through thick walls of steal, ray guns, warfare.

Little did we know, back then, of the more peaceful application for laser beams; transmitting gobs of information. Quietly pulsing under our feet through cables of fiber optic, lasers carry the conversations of the world. Millions of Youtube videos, e-mails, Skype calls, television shows and internet radio; the laser has made it possible.

Yes, it can still cut steel, can even be used in warfare, but information technology is what I see most often in 2010.
