Abstract:	非共線性光參數放大器(NOPA) 是在飛秒時間下用於時間解析光電子顯微鏡和能譜術的理想、可廣泛調變波長之光源。在這篇碩士論文中，構建了一個以時間解析光電子能譜術實驗為目標的NOPA 光源。該光源由中心波長約為1030奈米、脈衝長度為300 飛秒、重複頻率為1MHz 的雷射光源驅動。NOPA 光源的輸出波長範圍為630 至960奈米，這是由初始光源在釔鋁石榴晶體中產生的白光種子光束所決定。在這個 NOPA 光源的核心部分， β-硼酸鋇晶體由初始光源的二次諧波激發，而最後輸出再通過一對稜鏡以縮短脈衝長度，並使用另一個β-硼酸鋇晶體進行頻率倍增。 v;A non-collinear optical parametric amplifier (NOPA) is an ideal, widely-tuned light source for femtosecond time-resolved photoelectron microscopy and spectroscopy on surfaces. In this master thesis, an NOPA aiming at its application for pump-probe photoemission experiment has been built. The NOPA is driven by a fundamental laser source centered at around 1030 nm with a 300 fs pulse duration at a repetition rate of 1 MHz. The output of the NOPA has a wavelength range from 630 to 960 nm as given by its seed beam from the white light generation in an yttrium aluminum garnet plate driven by the fundamental beam. In the central part of this NOPA, a β-barium borate crystal is pumped by the second harmonic of the fundamental beam. The output of the NOPA is compressed by a prism pair to reduce the pulse duration, and its frequency is doubled by using another β-barium borate crystal.
