The phenomenon of collective recombination (superfluorescence or superradiance) of electrons and holes in semiconductor laser structures of various dimensions is reviewed. At the current level of technology, this phenomenon can be realized most easily in quantum-well and quantum-dot heterostructures. Under CW pumping, it could lead to the generation of powerful coherent radiation pulses which are shorter than incoherent relaxation times and have nothing to do with mode-locking technique. Particular attention is paid to the external magnetic field and distributed feedback of waves which favor suparradiant lasing.

We describe spectroscopic investigations of Cd1−XHgXTe:V:Mn crystals. It was shown that the electronic processes in this material are fast and occur in nanosecond range. These materials are very sensitive up to 1800 nm. The nature of the electronic transitions which determine their NIR photosensitivity was established.

We suggest a novel approach to achieve reversible nonreciprocal optical response in a periodic photonic structure with a pair of defects, one of them being a nonlinear liquid crystal. We show that nonreciprocal effects can be reversed by changing the wavelength due to change of localization properties of defect modes.

Radiation power for the combustion of carbon particles is measured at particles irradiation in air by a cw CO2 laser. For the medium in the form of a free vertical jet the dependences of the threshold radiation intensity for the evaporation of aluminium and carbon particles in nitrogen on their radius are obtained.

For the first time the energy level positions of Au I atoms have been measured with high accuracy by means of laser-microwave spectroscopy in the 176–211 GHz frequency range. The new measurements cover the range of principal quantum number n=31–34 for Rydberg series F5/2,7/2. Using our measured frequencies the quantum defect constants for this series are obtained. The description of our spectrometer, measurement technique and results are presented.
