Comparison of Yb:YAG crystals grown by CZ and TGT method
Five atomic percent Yb:YAG laser crystals have been grown by Czochralski (CZ) and temperature gradient technique (TGT) method. The absorption spectra of as-grown and annealed Yb:YAG crystals have been investigated. There is no Yb 2+ and color center absorption in TGT-grown Yb:YAG crystals; the absor...

Summary: | Five atomic percent Yb:YAG laser crystals have been grown by Czochralski (CZ) and temperature gradient technique (TGT) method. The absorption spectra of as-grown and annealed Yb:YAG crystals have been investigated. There is no Yb
2+ and color center absorption in TGT-grown Yb:YAG crystals; the absorption peak of CZ-grown Yb:YAG crystals after O
2-annealing at 255
nm is attributed to Fe
3+ ions. The longitudinal distribution of Yb
3+ ions has also been studied; TGT-grown Yb:YAG crystal has a larger distributing inhomogeneity of Yb
3+ although it is large sized. |
