我们报告了产生时间对比度为10（10）的几周期多太瓦光脉冲，当测量接近脉冲峰值2 ps时。在主脉冲之前的几十皮秒，对比度值的扩散预计会远远超出测量极限。对激光系统不同阶段对比度改善因子的单独测量表明，在脉冲峰值前50和25 ps分别测量时，真实对比度值可达到10（19）和10（14）。最短脉冲持续时间和最高对比度的结合使我们的系统成为未来多拍瓦激光设备的有前途的前端架构。(C) 2011美国光学学会
We report the generation of few-cycle multiterawatt light pulses with a temporal contrast of 10(10), when measured as close as 2 ps to the pulse's peak. Tens of picoseconds before the main pulse, the contrast value is expected to spread much beyond the measurement limit. Separate measurements of contrast improvement factors at different stages of the laser system indicate that real contrast values may reach 10(19) and 10(14), when measured 50 and 25 ps before the pulse's peak, respectively. The combination of the shortest pulse duration and the highest contrast renders our system a promising front-end architecture for future multipetawatt laser facilities.
