Deuterated L-arginine phosphate: a new efficient nonlinear crystal

Abstract

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 phasematchable. Over most of its usable frequency range, it is substantially more efficient than KDP. Crystals grown in large sizes (100 cm') 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.

Synthesis and crystal structure of guanidinium L-monohydrogentartrate: encapsulation of an optically nonlinear octupolar cation

“…One may also identify a guanidinium-like fragment as being the active part of the substituted L-argininium phosphate monohydrate crystal (Aoki, Nagano & Iitaka, 1971;Eimerl, Velsko, Davis, Wang, Loiocono & Kennedy, 1989).…”

Investigation of Some New Nonlinear Optical Crystals by Means of NQR, IR and X-Ray Diffraction Methods

“…The discovery in 1983 of the promising nonlinear optical and other properties [1] of crystalline L-arginine phosphate monohydrate (LAP) [3][4][5][6][7], (the symmetry and structure of which was determined earlier [2]) has lead to the search of analogues which might surpass LAP in some parameters [8][9][10]. In [8], an attempt was made to obtain LAP analogues by interaction of arginine with stoichiometric amounts of various acids.…”

Growth and Thermal Studies of Doped and Pure Crystals of L-Argininium Dinitrate

“…Ramasamy et al have determined the structure of L-argininium dinitrate (space group P2 1 ) and reported that the diprotonated argininium molecule is linked by a strong hydrogen bond to the nitrate anion [10]. Recently, Terzyan et al have also solved the structure of 2(L-arg.HNO 3 ).H 2 O and L-arg.2HNO 3 [11] .Recent experiments reveal that nonlinear performance can be improved by bringing out the compositional modification and metallic substitutions [12][13] …”
