The second-order susceptibility d(36) of ammonium dihydrogen phosphate (ADP) was determined from phase-matched second-harmonic generation (SHG) at two wavelengths. A cw single-mode He-Ne laser (λ= 633 nm) and a cw single-mode Nd:YAG laser (λ= 1064 nm) were used as fundamental beam sources. The results were d(36)(ADP, 633 nm) =(1.31 ± 0.05) ×10(-9) esu = 0.55 ± 0.02 pm/V and d(36)(ADP, 1064 nm) = (1.10 ± 0.06) × 10(-9) esu = 0.46 ± 0.03 pm/V. The d(11) values of α-quartz were determined relative to d(36)(ADP) to be d(11)(α-quartz, 633 nm) = (7.4 ± 0.3) × 10(-10) esu = 0.31 ± 0.01 pm/V and d(11)(α-quartz, 1064 nm) = (7.1 ± 0.3) × 10(-10) esu = 0.30 ± 0.01 pm/V by the use of the Maker fringe method. The Miller's delta ofADP and α-quartz is in good agreement at the two wavelengths.
通过在两个波长下进行相位匹配二次谐波产生（SHG），测定了磷酸二氢铵（ADP）的二阶极化率d(36)。使用连续波单模氦氖激光器（λ = 633 nm）和连续波单模Nd:YAG激光器（λ = 1064 nm）作为基波源。结果为d(36)(ADP, 633 nm) =(1.31 ± 0.05) ×10(-9) 静电单位 = 0.55 ± 0.02皮米/伏，d(36)(ADP, 1064 nm) = (1.10 ± 0.06) × 10(-9) 静电单位 = 0.46 ± 0.03皮米/伏。相对于d(36)(ADP)，通过使用马克条纹法测定α-石英的d(11)值，得到d(11)(α-石英, 633 nm) = (7.4 ± 0.3) × 10(-10) 静电单位 = 0.31 ± 0.01皮米/伏，d(11)(α-石英, 1064 nm) = (7.1 ± 0.3) × 10(-10) 静电单位 = 0.30 ± 0.01皮米/伏。在这两个波长下，ADP和α-石英的米勒δ值吻合良好。
