中文摘要	在飞秒激光频率梳系统中,通常采用自参考技术测量飞秒激光脉冲的载波包络相移,但该技术需要采用光子晶体光纤进行光谱扩展从而增加了系统的不稳定性,这种技术已经制约了高稳定度的飞秒激光频率梳的发展.采用PPLN晶体差频法测量了宽谱钛宝石振荡器输出的7fs激光脉冲的载波包络频移,得到了大于30dB的拍频信号,为研制无光纤的新一代高稳定度光学频率梳奠定了基础.; The self-reference technique is widely used to measure the carrier-envelope phase offset (CEO) of femtosecond laser pulses in the normal femtosecond laser frequency comb system. However, the instability of the frequency comb system is increased because the photonic crystal fiber is introduced into the system to broaden the spectrum of femtosecond laser pulses outside the cavity. In this paper, we presented another method to measure specifically the CEO for the broad spectrum Ti:sapphire oscillator with the pulse duration of 7fs, namely the difference frequency technique, with which we have obtained the beat frequency signal with a S/N ratio greater than 30dB. This provided a good precondition for the next generation of the femtosecond laser frequency comb system without the photonic crystal fiber.; 国家自然科学基金(批准号:60225005,60490280); 中国科学院知识创新方向性项目资助的课题~~
