Masers are astrophysical sources in which the absorption coefficient of the corresponding spectral line is negative and the radiation is amplified. For unsaturated sources, the amplification is exponencial. For saturated sources, the mtensity of radiation increases linearly with distance, or with the cube of the path lenght of saturation.
