摘要：
An electro-optic laser beam deflector with a clear optical aperture of 8.6 mm has been designed, realized, and tested. The electro-optic material used to implement the device was a MgO:LiNbO(3) crystal. The exceptionally large aperture makes the device suitable for applications where fast scanning of high power laser beams is needed. The measured deflection angle was 120 mu rad/kV for a total length of electro-optic material of 90 mm. A mode quality analysis of the laser beam revealed that the M(2) of the laser is affected by less than 4% during scan operation when maximum driving voltage is applied.
