Optical and laser Houses of Yb:Y2SiO5 single crystals and discussion on the figure of merit related to compare ytterbium-doped laser elementsThe thermal Attributes of orthorhombic AgGaGeS4 and chalcopyrite AgGaS2 crystals such as thermal growth, certain heat and thermal conductivity have already been investigated. For AgGaS2 crystal, We have now pr
