Did You know?

The first useful semiconductor laser was made by R.N. Hall in 1962 which was composed of GaAs materials that emitted in near infrared at 0.8 µm. The semiconductor laser is similar to transistor, has the appearance of a LED but the output beam has the characteristics of a laser. The application that was the main driving force in the development of semiconductor lasers was in the field of long distance communications but at this moment the use of this laser in compact disc players constitutes their largest single market. Using semiconductor laser gives an advantage of low power consumption requirements.
