title: Polarised infrared and Raman studies of YCa4O(BO3)3 a non-linear optical single crystal.
abstract: YCa4O(BO3)3-(YCOB) is a non-linear optical (NLO) material grown by Czochralski technique. Polarised IR, ATR-IR, polarised Raman and optical transmission spectral measurements were made. A series of absorption bands have been observed with intensities depending on the functional groups of the crystals. The observed bands were assigned and discussed.
