在本論文中,我們利用脈衝整形系統來進行超寬頻脈衝量測及多脈衝產生的研究。
利用脈衝整型系統配合Multiphoton intrapulse interference phase scan (MIIPS)方法量測超寬頻脈衝，在量測上，我們結合angle-dithering方法來解決超寬頻脈衝在MIIPS量測中所需倍頻晶體中的相位匹配(phase matching) 問題,利用較厚的倍頻晶體取代薄的倍頻晶體作晶體角度(angle-dithered)抖動,並對得到的倍頻訊號做量測週期時間上積分以得到完整的倍頻頻譜資訊,另ㄧ方面也可以得到較強的倍頻訊號，來使超寬頻MIIPS更為準確且完整。
脈衝整形系統的應用方面，利用脈衝整形系統調制光的振幅與相位來模擬分光鏡及時間延遲機制，取代以往的麥克遜干涉儀的兩道光束架構，來產生多脈衝和量測脈衝的時間波形，相較以往的方法，不僅降低了能量的損耗，在控制延遲時間τ的穩定度及時間解析度也獲得提升，我們也預期將可利用此方法在narrow-band frequency-tunable THz 電磁波產生上，也能得到更好的效果。

This thesis utilize pulse shaping in characterization of ultra-broad bandwidth laser pulse and multi-pulse generation.
Using angle-dithering technique, time-integrating phase-matching bandwidth can be increased significantly even with a thin crystal. We also characterize the pulse by angle-dithered MIIPS( intrapulse interference phase scan ) technique. An addition advantage of using a thick crystal is increased signal strength.
In addition, we provide a method to generate multi-pulses and proceed Michelson interferometeric autocorrelator by controlling the spectral amplitude and phase of the pulse. To compare with the past method, the efficiency was obtained from 33% to 80% , and the stability and time resolution of delay time can be improved. We expect this method applied to narrow-band frequency-tunable THz wave genetration will be better.
