我们已经在时间上的特点，色散补偿和载波包络相位稳定的1.4周期脉冲（3.2 fs）与160 μ J的能量在722 nm，使用最小和方便的色散扫描设置。该装置是全在线的，不需要干涉分束，并使用大多数激光实验室提供的组件。使用在水中传播的三阶色散的宽带最小化使得能够使用相同的啁啾镜组将压缩脉冲持续时间从3.8 fs减少到3.2 fs。载波包络相位稳定的倍频程跨越脉冲也进行了色散扫描设置。这种前所未有的简单和可靠的方法提供了可重复的CEP稳定脉冲在单周期制度的应用，如CEP敏感光谱和隔离阿秒脉冲产生。2014美国光学学会Optical Society of America
We have temporally characterized, dispersion compensated and carrier-envelope phase stabilized 1.4-cycle pulses (3.2 fs) with 160 mu J of energy at 722 nm using a minimal and convenient dispersion-scan setup. The setup is all inline, does not require interferometric beamsplitting, and uses components available in most laser laboratories. Broadband minimization of third-order dispersion using propagation in water enabled reducing the compressed pulse duration from 3.8 to 3.2 fs with the same set of chirped mirrors. Carrier-envelope phase stabilization of the octave-spanning pulses was also performed by the dispersion-scan setup. This unprecedentedly simple and reliable approach provides reproducible CEP-stabilized pulses in the single-cycle regime for applications such as CEP-sensitive spectroscopy and isolated attosecond pulse generation.
