Refractive indices and their dispersion in the wavelength range from 365 nm to 2325 nm and transmission ranges of the tetragonal melilite‐type germanates Sr 2 MgGe 2 O 7 , Sr 2 ZnGe 2 O 7 and Ba 2 ZnGe 2 O 7 were determined. The uniaxial positive crystals Sr 2 MgGe 2 O 7 and Ba 2 ZnGe 2 O 7 both offer the possibility for phase matched second harmonic generation, a detailed analysis of phase matching conditions is given. The refractive indices of Sr 2 ZnGe 2 O 7 show an isoindex (isotropic) point at 467 nm. The investigation was performed on Czochralski grown large single crystals. The crystal structure of all three germanates were determined by means of X ‐ray diffraction. The results corroborate unmodulated melilite‐type structures at room temperature.
