The present disclosure provides a device for reducing residual amplitude modulation. The device includes an electro-optic modulation device with three crystals connected in series. The three crystals are the first cubic crystal, an intermediate crystal, and the second cubic crystal respectively. The intermediate crystal is an electro-optic modulating crystal. The intermediate crystal is connected to the high-frequency signal source module. The specification of the intermediate crystal is X mm&#xd7;Y mm&#xd7;d mm. The first cubic crystal and the second cubic crystal is connected to both ends of the intermediate crystal in series along the direction of the X axis. The relative dielectric constant of the first cubic crystal and the relative dielectric constant of the second cubic crystal both are equal to the relative dielectric constant of the intermediate crystal. The specification of the first cubic crystal and the specification of the second cubic crystal both are d/2 mm&#xd7;Y mm&#xd7;d mm.
