Figures & data
Figure 1 Effect on the signal when changing the polarity of the high voltage on the BSO crystal. (The color version of this figure is included in the online version of the journal.)
Figure 2 The formation of an index grating due to an intensity grating in a photorefractive crystal: intensity grating (a), electron density (b), space charge (c), space charge field (d) and first Fourier component of the index grating (e). Positive voltage: blue solid lines, negative voltage: red dashed lines. (The color version of this figure is included in the online version of the journal.)
Figure 3 Schematics of the quasi-balanced two-wave mixing interferometer setup (a) and of the voltage inverter H-bridge (b). (The color version of this figure is included in the online version of the journal.)
Figure 4 Comparison between normal measurement (a) and quasi-balanced measurement (b). Suppression of electrical noise at approx. 0.2 μs is observed.
