The visible second harmonic of the idler output from a noncollinear optical parametric amplifier was compressed using adaptive dispersion control with a deformable mirror. The amplifier was pumped by and seeded in the signal path by a common 400 nm second-harmonic pulse from a Ti:sapphire regenerative amplifier. Thus, both the idler output and the second harmonic of the idler were passively carrier-envelope phase stabilized. The shortest pulse duration achieved was below 3 fs.
利用变形镜进行自适应色散控制，压缩了非共线光参量放大器的闲频光输出的可见二次谐波。该放大器由钛宝石再生放大器产生的 400nm 二次谐波脉冲泵浦，并在信号通路上对其进行种子注入。因此，闲频光输出及其二次谐波都实现了被动载波包络相位稳定。获得的最短脉冲持续时间低于 3fs。
