啁啾脉冲频谱相位的测量方法
|
摘要
啁啾脉冲频谱干涉仪(CPSI)是一种单发超快诊断仪器,其中采用大啁啾量的参考、探测脉冲并准确测量其频谱电场是仪器同时实现超高时间分辨和大量程测试的关键因素。基于变换极限飞秒脉冲和啁啾脉冲之间的频谱干涉,通过理论和数值计算研究提出了一种用于大啁啾量脉冲的频谱相位测量的线性光学测量方法,称之为非对称频谱干涉法。研究表明,当利用非对称频谱干涉法测量啁啾脉冲频谱干涉仪中的啁啾脉冲频谱相位时,时间延迟的平移误差和相对较小的飞秒脉冲啁啾会使测量结果产生一阶相位误差,并由此导致啁啾脉冲频谱干涉仪测量时域信号的结果产生时间上的平移,但是所测信号的相对时间演化过程不受其影响。
Chirped pulse spectral interferometer(CPSI)is an ultrafast single-shot diagnostic instrument,the large chirped pulses reference,pulse detection and accurate measurement of its spectral of electric field are critical factors to realize ultra-high time-resolution and large range of testing simultaneously.Based on the spectral interference between transform limit femtosecond pulse and chirped pulse,a linear optical measurement method for spectral phase measurement of large chirp pulse is proposed by theoretical analysis and numerical calculation.It is called asymmetric spectral interference method.Investigations show that when employing the asymmetric spectral interference method to measure the spectral phase of chirped pulses in CPSI,translation error of the time delays and relative smaller chirp of femtosecond pulse will produce a first order phase error.Consequently,the time-domain signal measured by CPSI will generate a time translation,but the relative time evolution of the measured signal is not affected.
