On the electro‐optic properties of single crystals of sodium, potassium and rubidium acid phthalates

Abstract

The linear electro-optic (Pockels) effect in a series of alkali metal acid phthalate crystals has been studied. Single electro-optic coefficients rT13 and r:,, for sodium (NaAP), potassium (KAP) and rubidium (RbAP) acid phthalates have been measured by employing the modified Mach-Zehnder interferometric technique. The best electro-optic crystal in this series is RbAP with r~l, =9.10x10-12mV-1, r~3 3 = 3 . 0 5 x 1 0 -1 2 m V -1 and a sizable figure of merit for electro-optic phase retardation, comparable with that of KDP. The dispersion properties of the electro-optic coefficients for KAP are discussed in detail.

Influence of Amino Acid Dopants on the Growth and Properties of Potassium Hydrogen Phthalate Single Crystals for Nonlinear Optical Applications.

“…5(2), 886-897 887 Potassium hydrogen phthalate (KHP) are widely hired in the subject of x-ray spectroscopy as a monochromator and additionally as an analyzer. KHP exhibits pyroelectric, piezoelectric, elastic, nonlinear optical (NLO) properties, elasto-optic [3] and electro-optical studies on a sequence of alkali substituted hydrogen phthalate crystals which included it [4] and it crystallizes in an orthorhombic crystal structure with space group Pca2 1 [5]. KHP has platelet morphology with perfect cleavages alongside the (010) plane.…”

Investigation on Synthesis, Growth, Structural and Optical Properties of a New Semiorganic Crystal 2-Aminopyridine Potassium Hydrogen Phthalate (2APKHP)

“…Monaco et.al, have reported the formation of 1:1 molecular compounds between amino acid and many different acids [15][16][17][18][19]. Potassium hydrogen phthalate crystals are playing an important role in the field of nonlinear optic materials, they are known SHG material that have long stability in devices due to their electro-optic properties and exhibit interesting in piezoelectric, pyroelectric and elastic properties that are useful in many applications [20][21][22][23]. Pyridine is a heterocyclic organic compound with the chemical formula C 5 H 5 N. Intensive studies on pyridine and pyridine derivatives have been made in the past, keeping in the view of their industrial importance both as fundamental building block and reagent in organic synthesis [24].…”
