Optical and laser Houses of Yb:Y2SiO5 solitary crystals and discussion of the determine of advantage pertinent to match ytterbium-doped laser materialsThe thermal Homes of orthorhombic AgGaGeS4 and chalcopyrite AgGaS2 crystals including thermal expansion, specific warmth and thermal conductivity happen to be investigated. For AgGaS2 crystal, We now
