S. Romani et al., EVALUATION OF THE EFFECTIVE 2ND-HARMONIC GENERATION COEFFICIENT OF MONOMETHYL UREA SINGLE-CRYSTALS, Physica status solidi. b, Basic research, 197(1), 1996, pp. 271-276
The effective second harmonic generation coefficient of monomethyl ure
a has been determined relatively to urea by phase matched interaction.
Both Type I and Type II phase matching have been achieved by propagat
ing the pump beam at small angles to natural faces of solution grown c
rystals. The conversion efficiency for the doubling of Nd:YAG fundamen
tal is similar in urea and methyl-urea.
