Abstract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.
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.
