Optical, spectral, and generation characteristics as well as the degradation threshold experienced under laser radiation are investigated for alexandrite crystals grown by horizontally directed crystallization (HDC) in molybdenum containers. Various properties and qualities of HDC alexandrite crystals are compared with those of crystals obtained by the Czochralski technique. It is demonstrated that the HDC alexandrite crystals have a lower uncontrolled iron impurity and weaker UV-absorption than the alexandrites grown by the Czochralski method, which allows the pumping lamp irradiation to be used more effectively. A lower concentration of opaque inclusions and a higher degradation treshold under laser radiation are noted, as well as the dependency of energy characteristics of HDC alexandrite lasers on periodical growth-structure orientation in relation to the cavity axis.
