中文摘要：
将基频光与其自身的倍频光合成，是一种得到超过一个倍频程的超宽光谱的简单方法，而载波-包络相位（CEP）对合成超宽光谱产生的超短脉冲有重要的影响．本文从光频梳的角度，根据钛宝石激光器中产生的超短脉冲光谱，计算载波-包络相位对该脉冲与其自身的倍频脉冲合成产生的超短脉冲的影响，说明了调整载波-包络相位对于脉冲合成的重要性．
英文摘要：
Ultrabroadband spectrum is necessary for generation of ultrafast laser pulses; however, the extent of broadening the spectrum by its own nonlinear effect, such as self-phase modulation or cross phase modulation etc., is always limited. An easy way to broaden the spectrum to an octave is synthesizing the spectrum of its second-harmonic and the spectrum of itself. In this paper, influence of carrier-envelope phase on the synthesizing of two laser pulses is studied.
