A number of definitions of entropy in optics have both advantages and disadvantages. The major features of different entropy definitions are briefly characterized. The principal distinction between the statictics entropy definition and the thermodyna

The electromagnetic irradiation of Terahertz (THz) frequency could be obtained by means of optical rectification, using the media with non-linear properties. We demonstrated that the semiconductor crystal (GaAs) with heavy-ion induced defects (irradi

The general conditions of brightness and radiation temperature increasing are discussed. It is shown that such an increase is possible in non-inverted medium, and perhaps actually takes place for some extremely bright astrophysical sources excited by

GaAs crystals with nanochannels produced as a result of heavy-ion irradiation at the energy of 100 MeV demonstrate a giant (more than 15 times) increasing of efficiency of the THz surface emission. The efficiency strongly depends on the fluence, orie
