我们报告了使用二阶光谱全息术的飞秒光信号处理。热塑性板增强的二阶衍射使得一阶全息术无法实现的新信号处理操作成为可能。描述了导致输出波形等于输入波形的自卷积函数的实验，并讨论了为超快光信号实现简单关联存储器的可能性。
We report femtosecond optical signal processing by using second-order spectral holography. Enhanced second-order diffraction from a thermoplastic plate makes possible new signal-processing operations not possible with first-order holography. Experiments resulting in output waveforms equal to the autoconvolution function of the input waveform are described, and the possibility of implementing a simple associative memory for ultrafast optical signals is discussed.
