We propose and experimentally demonstrate an original method to analytically retrieve complete spectral phase of ultrashort pulses by measuring two modified interferometric field autocorrelation traces using thick nonlinear crystals with slightly different central phase-matching wavelengths. This new scheme requires no spectrometer, detector array, nor iterative data inversion, and is compatible with periodically poled lithium niobate (PPLN) waveguide technology offering potential for high measurement sensitivity.
我们提出并通过实验证明了一种原始方法，即利用具有略有不同中心相位匹配波长的厚非线性晶体测量两条修正的干涉场自相关迹线，来解析检索超短脉冲的完整光谱相位。这种新方案不需要光谱仪、探测器阵列，也不需要迭代数据反演，并且与周期性极化铌酸锂（PPLN）波导技术兼容，具有高测量灵敏度的潜力。
