WASHINGTON -- This weekend marks the 50th anniversary of the invention of the first working laser. Today, lasers can be found almost everywhere, from telephone lines to cutting edge scientific research, supermarket scanners, and even cat toys. The first laser light was produced on May 16, 1960 at the Hughes Research Lab in Malibu, California when Theodore Maiman switched on his fist-sized device that flashed a bright red spot onto a photo-detector. Since then, lasers have become smaller, more powerful, and ubiquitous in modern technology.
