Fast Sweeping Device for Laser Bunch

An electro-optical laser sweeping device directs the head and the tail of a laser bunch into different frontal directions, so at some distance, the laser bunch becomes tilted with respect to forward direction. For sweeping of a laser bunch having 300 ps duration up to 10 mrad, the voltage drop along the laser bunch must be ∼ 10kV. The repetition rate desirable for this type of device used in laser acceleration or generation secondary back-scattered electrons is up to 1 MHz. Details of this scheme are described here.
