Abstract

The properties of lasers based on the double molybdates and tungstates of alkaline rare-earth metals activated by trivalent neodymium ions are analyzed for free lasing and Q-switching modes. The physical, optical, and spectral-luminescence properties of crystals are covered. The energy and spectral characteristics of these lasers, and the dependence of their variations on the concentration of the activator are investigated. It is observed that Nd-doped potassium-gadolinium tungstate and potassium-yttrium tungstate lasers are more efficient under pulsed low-frequency pumping than Nd-doped yttrium-aluminum garnet lasers. It is concluded that such a phenomenon is caused by higher values of the laser transition cross sections and by higher optical homogeneity.
