Abstract
In an embodiment, an optical deflection device includes: an electro-optic crystal comprising KTaNbO, the electro-optic crystal having a first surface and a second surface, the first surface and the second surface facing each other; a first electrode on the first surface of the electro-optic crystal; a second electrode on the second surface of the electro-optic crystal; a power source configured to output a control voltage for forming an electric field inside the electro-optic crystal via the first electrode and the second electrode; and a light source configured to emit a pulse laser to be incident on the electro-optic crystal along an optical axis, the optical axis substantially perpendicular to a direction of the electric field formed by the control voltage, wherein a peak power density of the pulse laser output from the light source at a light incidence surface of the electro-optic crystal is less than 800000 W/cm.
