And The Beam Goes On…50th Anniversary of The Laser

May 15, 2010, By Alex Ion

The laser has been around for fifty years. The laser is defined as any of several devices that emit highly amplified and coherent radiation of one or more discrete frequencies.

One of the most common lasers makes use of atoms in a metastable energy state that, as they decay to a lower energy level, stimulate others to decay, resulting in a cascade of emitted radiation.

The very first laser was designed, built and functional by Theodor Maiman in May 16, 1960 at the Hughes Research Lab. This was the first pulsating laser demonstration.

The laser has many uses and has improved society in many different ways. In the medical field, the laser is used in cosmetic surgery to remove scars, tattoos, and other skin defects, the removal of tumors is done by lasers, and corrective eye surgery. In the scientific and military field, the laser is used for cooling, microscopy, laser sight, distance measurement, and many other uses.

Lasers play an integral part in our society. The cd, dvd, and blu-ray disc have made the use of listening to music and watching movies extremely easy.

We should take a minute and be happy to know that the laser has improved our lives.
