Figure 6
Two plots of the Δθ1λ/A1 characteristic values versus B1/A1 ratio for the (100) (red open circles) and (010) (blue solid circles) plates of the pure KDP crystal. The slopes of the fitted lines are equal to −k − a = (0.48 ± 0.02) × 10−3 for the (100) plate and −k − a = −(0.41 ± 0.05) × 10−3 for the (010) plate. The intercepts of the fitted lines give k − p = −(0.43 ± 0.05) × 10−3 and (0.36 ± 0.02) × 10−3, respectively. |
