Fig. 3: THz production with varying wafer counts.
From: Highly scalable multicycle THz production with a homemade periodically poled macrocrystal

In (a), the THz pulse energy scaling as a function of the number of wafers is illustrated. The absorption g = 1.86 × 10−3 THz−1 is fitted with Eq. (3) (see “Methods”). In (b), autocorrelation traces for 1, 2, 6, and 12 wafers in the stack are presented. The error bars on our figures reflect the square root of the sum of the squares for these uncorrelated errors (see “Methods”).
