Abstract

We demonstrate three new electrooptical pulse synthesizing methods to generate arbitrarily shaped optical pulses in the picosecond range from cw lasers using an electrooptic modulator or a deflector. They utilize (1) separation, control, and composition of each sideband component of the phase-modulated light using two gratings and a spatial filter, (2) selection of produced sidebands using an FP filter, and (3) control of near-field pattern of an elctrooptically deflected beam using a spatial filter and composition using a grating or a slit. Using these methods picosecond pulses at 9.4-75GHz repetition frequency have been generated.
