Optimized single amplified ultra-short laser pulse

Abstract

Single amplified ultra-short laser pulse is very important in basic scientific researches as well as in ultra-high power laser applications. The high intensity ultra-short laser pulse usually comes from the mode-locked pulses train. It is important to develop a laser amplifier configuration that can optimally amplify single ultra-short laser pulse. We present in this research, first by controlling the synchronization of the amplifiers chain, and then optimally adjust the shape of amplified spontaneous emission of each amplifier, we can select the single amplified ultra-short laser pulse out of the seed ultra-short pulses train and boost the laser pulse to the maximum power amplification. An adjustable repetitive single pulse high intensity ultra-short pulse UV laser system was developed and the laser outputs were extracted at various ends and characterized in detail.
