The LiYF 4 single crystal codoped with thulium and holmium ions was successfully grown by the Cz method. The optimal technical parameters obtained were as follows: the pulling rate was 0.16 mm/h; the rotation speed was 3 rpm; the cooling rate was 15 °C/h. The result of XRD curve showed that as-grown Tm,Ho:LiYF 4 laser crystal belonged to the monoclinic system with scheelite-type structure...
The 10 at.% Er 3+ -doped KYb(WO 4 ) 2 (KEr 0.1 Yb 0.9 (WO 4 ) 2 ) laser crystal with dimensions up to 25 mm × 15 mm × 10 mm was grown by the Kyropoulos method. The crystal structure was identified as β-KEr 0.1 Yb 0.9 (WO 4 ) 2 by XRD analysis. Through TG-DTA curves, the melting point and transition point of the...
