A crystal of the non-linear and laser matrix Ca4GdO(BO3)(3) (GdCOB) was gro
wn by the Czochralski technique and polarized Raman scattering spectra were
measured along its crystallophysic optical axes. A vibrational assignment
is proposed in correlation with the two crystallographic types of (BO3)(3-)
groups that are responsible for the non-linearity of the matrix. Copyright
