| dc.description.abstract | 目前本實驗室已經可以利用脈衝雷射的近紅外光聚焦在氣體上使用高階諧波的機制穩定產生極紫外光的光源，並且使用實驗室自制的極紫外光光譜儀量測高階諧波產生的極紫外光的波長，光子數和發散角。
我們在此設計固態靶材的雷射光電輔助效應實驗量測出高階諧波產生的極紫外光脈衝時寬。我們建造一個超空真空度的實驗站和飛行時間能譜儀，來完成這項實驗。配合此實驗需要，本實驗站有：為清潔靶材的加熱冷卻系統，及高能量解析度的飛行時間能譜儀，和兩道雷射光空間-時間疊合及觀察雷射光聚焦的診斷裝置。
本論文將介紹中央大學強場物理與超快技術實驗室高階諧波產生實驗站，和其相接的超高真空實驗站的硬體架設與設計、雷射輔助光電效應的原理與應用、實驗的方法與步驟、最後的結果與討論。
我們已完成：如何穩定產生高強度極紫外光，有效率進行靶材清潔，以及利用近紅外雷射光對光電子的影響觀察到雷射輔助光電效應。

| dc.description.abstract | We can produce EUV light by use near infrared pulse laser to focus at the gas target in our laboratory. The way product EUV light we called High Harmonic Generation. We use homemade flat-field spectrometer to measure the wavelength and divergence angle and photon number. Now we want to know the pulse duration of EUV light. Therefore we design an experiment to measure the pulse duration of EUV light.
I build the experiment station for this experiment. We can do many things at the station. We have ultra high vacuum in the station because we want to use solid target. In the ultra high vacuum we can keep the target clean a few hours. And then we have a procedure for target clean including heating and cooling.
The most important we also build a spectrometer, called Time-of-flight spectrometer. The spectrometer connected to the experiment station which I builded . We can measure the kinetic energy of particle by time-of-flight spectrometer. And then we can later take time-of-flight to atomic and molecular physics experiments.
