Summary form only given. One of the drawbacks for further output power scaling with these crystals is comparatively low thermal conductivity and large thermal lensing at high pump powers. However, the thermal lensing depends on thermo-optical properties that are strongly anisotropic in double tungstates and could be reduced in certain directions. Here we present the results of the investigation of...
The temperature dependence of three principal refractive indices of the biaxial KGd(WO4)2 and KY(WO4)2 crystals in the temperature range of 288–673 K was measured at wavelengths of 438.5 and 632.8 nm. Their thermo-optical coefficients (TOC) of the first and second orders were determined on the basis of the experimental data obtained. TOC were found to be negative for the ng and np refractive indices...
Single crystals of the CuIn 5 Se 8 compound have been synthesized by the directed crystallization of the melt in a single-zone furnace (vertical Bridgman variant), starting from the stoichiometric mixture of constituent elements. Phase purity of the synthesized material was confirmed by powder X-ray diffraction. Transmittance as a function of wavelength was recorded in the wavelength...
