Interband Phototransitions Involving Free Electrons: III. Transmission of Light through Crystals

摘要

It has been shown that the two-electron mechanism of nonlinear optical absorption considered in the first two parts of our study, even at laser radiation intensities j ～ 10~3-10~4 W/cm~2 in the case of nanosecond pulses, can lead to almost complete absorption of light by crystals that are transparent to weak radiation of the same wavelength. A number of materials that can exhibit the considered effects have been described.
