摘要

A high-contrast preamplifier based on optical-parametric amplification with a short pump pulse is demonstrated.A gain larger than 10~(5) and measurement-limited contrast higher than 10~(11) are obtained over a large temporal range extending within less than 10 ps of the peak of the pulse, because of the high instantaneous parametric gain provided by a short pump pulse in a nonlinear crystal. The energy gain and high contrast of this preamplifier make it a good seed source for high-power laser systems.
