Origins of lasers Theodore Maiman showed the world the first working laser in 1960. The idea, however, was introduced by the one and only Albert Einstein. The first laser was a ruby laser. Diagram above.

How do lasers work? A laser is activated by a few photons. These active photons cause more and more photons to get “excited” and thus creating a laser beam. Laser beams are usually the same color as opposed to light.

When you watch an average tv today, you can only see 30-35% of the ACTUAL color content New developments in laser technology will allow you to see 90% of color content! Cheaper as well.
