Deuterated L-arginine phosphate: a new efficient nonlinear crystal

Deuterated L-arginine phosphate (d-LAP) is a highly transparent monoclinic crystal with attractive properties for efficient frequency conversion. It is grown easily from aqueous solution, and it is phase-matchable for all nonlinear processes where KDP is phase-matchable. Over most of its usable frequency range, it is substantially more efficient than KDP. Crystals grown in large sizes (100 cm/sup 3/) have a high damage threshold, excellent optical quality, are less hygroscopic than KDP, and are easily fabricated into nonlinear devices. Deuterated LAP is attractive for harmonic generation of Nd lasers and for work in the ultraviolet down to about 250 nm.<
