ABSTRACT

Early in the history of ultrashort light pulse techniques, the application of electro-optic modulators as a chirping mechanisms was explored by many researchers [8-11]. ™is technique of pulse chirping, combined with newer approaches to dispersive delay lines and the feverish pace of short pulse technology,
