摘要：
A technique to determine D/H diffusion profiles in DKDP frequency conversion crystals based on micro-Raman spectroscopy was discussed. The method allows to correlate Raman peak positions to deuteration levels in the DKDP crystals. The technique is fast, inexpensive, and works under various environmental conditions allowing better understanding and controlling deuterium depletion in DKDP crystals. The results showed that the shift of the totally symmetric PO 4 stretch mode in the Raman spectrum of DKDP crystals scales linearly with the degree of deuteration.
