线性扫频光脉冲功率谱的理论分析

Theory of power spectrum of linear frequency-swept optical pulses

本文给出了线性扫频(啁啾)的高斯型光脉冲的功率谱表达式,它等效于有调制的、脉宽压窄的无啁啾光脉冲的功率谱.理论分析表明:啁啾可由脉冲的功率谱并借助强度自相关方法确定.

Expressions of the power spectrum of linear frequecy swept Gaussion pulses are given which are equivalent to the power spectrum of the modulated and compressed light pulses without ohirpping. The chirp ping be can determined by means of the power spectrum and the standard intensity autocorrelation.
