| 摘 要： | 讨论了一种测量飞秒激光脉冲啁啾的简单方法的可行性,采用对干涉自相关(IAC)做频谱修正,得到干涉自相关修正光谱(MOSAIC),利用该修正光谱对啁啾有很高灵敏度的特性,检测到了略偏离变换极限的飞秒激光脉冲中含有的微小啁啾。MOSAIC能够精确地测量飞秒激光脉冲的微小啁啾量。

| Abstract: | A simple technique which can measuring the chirp of femtosecond laser pulses is described.Modified spectrum autointerferometric correlation(MOSAIC) uses spectral filtering of the interferometric autocorrelation(IAC) to render a waveform that is highly sensitive to chirp.Chirp could be shown visually in close to the width of the transform-limited pulse.Low chirp of femtosecond laser pulses can be determined accurately by using the MOSAIC. |
