dc.description.abstractStokes and anti-Stokes Raman spectra of green additively colored (with Ca) $SrF_{2}$ were recorded at $90^{\circ}K$ and $300^{\circ}K$ in the perpendicular scattering configuration using a He-Ne laser ($6328{\AA}$) as the excitation source. The spectrum consists of two parts. A relatively strong band appears at $284 cm^{-1}$ (at $300^{\circ}K$), which is also observed in pure $SrF_{2}$. This band is due to the first order Raman scattering by the $F_{1g}$ type mode at $k \sim O$. The rest of the spectrum consists of three bands at 117, 173 and $338 cm^{-1}$, and are not observed in pure $SrF_{2}$ crystals. These are assigned to the impurity induced (otherwise forbidden) critical point phonons corresponding to zone boundary TA, LA and LO respectively.en_US
