Description
Summary:Cesium hydrogen L -malate monohydrate crystals are shown to be a promising material for several potential applications. The crystals display an exceptionally large piezoelectric coefficient, d 22 = 23.7 pm ∕ V . They are also an efficient generator of the optical second harmonic of near infrared light, being close to an order of magnitude more efficient than potassium diphosphate crystals. A relatively strong electro-optic response (the figure of merit 1 2 ∣ n 1 r 12 − n 3 r 32 ∣ was found to be 4.83 pm ∕ V ) and a reasonable pyroelectric coefficient ( p 2 = 2.5 × 10 − 4 μ C ∕ cm 2 K at 245 K ) are also observed.
