First edition of this groundbreaking paper in which the first demonstration of a coherent light emission from a semiconductor diode or laser diode is presented. The semiconductor laser is built upon Gallium arsenide (GaAs) which is a compound of the elements gallium and arsenic. It is a III/V semiconductor, and is used in a wide variety of devices such as microwave frequency integrated circuits, monolithic microwave integrated circuits, infrared light-emitting diodes, laser diodes, solar cells, and optical windows.Later advances and improvements in materials has made the injection laser a fundamental and essential device in many important systems such as DVD- and CD-players.
