In this study, we experimentally study the dependence of the intensity of laser radiation incident on and transmitted through a layered InSe crystal. A picosecond YAG:Nd[Formula: see text] laser with a parametric light generator was used as a light source, making it possible to generate light pulses with a duration of [Formula: see text]30 ps, tunable in frequency within the range of 0.75–[Formula: see text]m. Optical bistability in the region of exciton resonance was detected in an InSe crystal at room-temperature under the picosecond YAG:Nd laser. It is shown that the decrease in absorption in the exciton resonance region is associated with the process of exciton–exciton interaction, shielding of excitons, and the Mott transition.

The field of journalism in Azerbaijan is vastly understudied. Aiming to fill the major knowledge gap owing to the lack of any empirical data on Azerbaijan’s media, this is an attempt to systematically study the media environment in Azerbaijan. Through a national survey based on the larger frameworks of the Global Journalist (GJ) and the Worlds of Journalism (WoJ) projects this study constructs a demographic profile of journalists in Azerbaijan. We find that the overall picture of journalism in Azerbaijan is, in many ways, similar to the global averages (i.e. education, ethnic and religious affiliation with majority groups). However, even when the findings are similar between Azerbaijan and other countries, especially the “Western” countries with particular media systems, similar demographic characteristics can be due to a set of factors specific to Azerbaijani society.
