A method of amplifying electromagnetic radiation is proposed, based on the use of induced emission phenomena, theoretically developed by A. Einstein in 1917. At the given method of amplification there is no conversion of energy of amplified radiation into other forms of energy. The method is suitable for amplification of ultraviolet, visible, infrared radio range waves. To bring the described amplification method into realization, a medium is produced having a negative absorption factor for radiations. The intensity of the radiation stream, passed through such a medium, rises, which produces the amplification effect. The amplification factor equals e to the KL, where K is the absorption coefficient and L is the thickness of the layer.
