| Single crystals of SrLaGaO4 and SrLaGa3O7 singly doped with Nd and codoped with Nd and Yb have been grown by the Czochralski method. Both the compounds form tetragonal crystals but belong to different space groups. A common feature of these matrices is a structural disorder resulting from statistical distribution of Sr2+ and La3+ ions over the lattice sites. A previous investigation of a laser diode pumped SrLaGa3O7:Nd laser revealed that inhomogeneous broadening of spectral lines of Nd3+ was advantageous for optical pumping and did not influence adversely the extraction efficiency. The present paper deals mainly with optical properties of Yb3+ ions which are of interest for the design of lasers pumped by a diode laser and operating near 1 μm. |
