Abstract- Nd:YAG crystals with various concentration of Nd (0.6 – 1.1 at%) have been grown by Czochralski method. The concentration of Nd dopant and its effective distribution coefficient (keff) in Nd:YAG crystal were measured and calculated by using optical absorption method. The results show that Nd:YAG crystals grown with similar growth parameters have constant keff=0.237. Moreover, the effective distribution coefficient of Nd dopant is independent on its initial concentration in melt.
Keywords: dopant concentration, distribution coefficient, absorption spectrum, Nd:YAG crystal.
