Static temperature gradient method has been developed for determining the thermal resistance of laser materials. The scheme of the method is maximally close to actual conditions under which the laser active element operates. The method has been teste

We studied a miniature laser source with an end-fed semiconductor pump in pulsed-periodic and cw mode; the pump had an active element that consisted of a KGd(WO4)2:Nd3+ crystal lasing at wavelength 1.35 μm. The laser power was studied as a function

Various ways to create a master radiator at wavelength 1.315 μm are considered, and its optimum construction layout is chosen, based on obtaining efficient emission of the second Stokes component in a stimulated-Raman-scattering solid-state laser. A

It is of much difficulty to provide efficient lasing on YAG:Er3+ crystal at the shorter wavelength transition (2.69 µm) of the 3µm-lasing spectrum of Er3+ due to high value of I 13 / 2 4 level lifetime and because of cross-relaxation. Codoping the

The local inhomogeneities Δχ(2) of the quadratic nonlinear susceptibility tensor in the KTiOPO4 (KTP) crystal have been investigated. A method for visualizing the nonlinear-optical inhomogeneities is proposed that makes it possible to observe monod

Effective methods have been developed for strengthening LiYF4:Nd laser crystals by chemical etching and film deposition. The samples were tested by two methods: the thermal-impact method and the static-gradient method. Besides this, laser testing of

This paper discusses the etching kinetics of a LiYF4:Nd3+ crystal in HNO3 solutions at various etchant concentrations and temperatures. The etching rates of the crystal along the three principal crystallographic directions are determined. The resulti

Induced second-harmonic generation has been observed in a number of colored glasses with high lead content, at efficiencies that are an order of magnitude higher on the average than in germanium silicate preforms for optical fibers. This highest coef
