Synchronizing a picosecond laser pulse with a nanosecond one would be useful in laser fusion research. Amplitude modulation of a picosecond spectrum makes this possible; this passive technique has already been studied by C. Froehly and demonstrated by B. Colombeau. It is shown here that this kind of pulse shaper is usable on a power laser chain. Starting from a 40-psec pulse, several pulse shapes with durations up to 640- and 40-psec rise time have been obtained at different power levels. Efficiency and signal to noise ratio of the system have been studied. The diffraction-limited beam has been amplified in a power laser chain.
Molded metallic mirrors manufactured by the so-called Optic-Replication Technique (ORT) are developed since a quite long time (ref 1-2-3) for various applications. Such mirrors are particularly attractive when attempt are made to consider large number of identical components associated with a low cost investment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
