摘要
A new type of Yb:KY(WO4)2 single crystal for laser is prepared by using a top seeded solution growth (TSSG) method from K2W2O7. The Yb:KYW polycrystal powder sample is generated by sintering at 900°C for 24 h and the K2W2O7 flux is formed by sintering at 600°C for 18-20 h. Based on the habit of crystal growth, the crystal with b orientation is selected as the seed. It is found that there are two obvious absorption peaks at 1045°C and 1010°C, a melting point at 1045°C and a phase transition peak from tetragonal to monoclinic at 1010°C according to TG-DTA. The crystal grew is the Yb:KYW crystal of low temperature phase with monoclinic system according to X-ray diffraction spectrum.
