AA-20DD自相關儀
AA-20DD實時自相關提供了飛秒和皮秒脈沖持續(xù)時間平穩(wěn)和快速的測量。自相關器可以通過使用最多4個可互換的光電檢測器和光學器件包括一些波長范圍。兩個獨立的范圍內(nèi)，也可根據(jù)要求覆蓋。輸入脈沖持續(xù)時間為20 fs到30 ps的，便于監(jiān)控不同的激光系統(tǒng)，尤其是飛秒和皮秒振蕩器（用于放大器監(jiān)控也請看到我們的ASF-20單次自相關）。
該器件具有USB接口，可以很容易上鉤最多使用Windows操作系統(tǒng)的PC，虛擬儀器的驅(qū)動程序也包含在包中。該軟件是隨設備一起提供，并包括幾個有用的工具。被收購的脈沖持續(xù)時間的數(shù)據(jù)可以可視化，存儲或?qū)С龅轿谋净騞at文件。計算并顯示在實時自相關函數(shù)和飛秒最后 FWHM 脈沖持續(xù)時間。此外，Gaussian or sech2接頭選項被啟用，強度函數(shù)也可以觀察到。統(tǒng)計瀏覽器功能允許從幾個不同的脈沖測量獲得的數(shù)據(jù)進行比較。
對AA-20DD的微小的身體地適用于任何實驗設備與嚴格的空間要求。我們還提供了可選的光纖輸入各種光纖快速和可靠的脈沖持續(xù)時間的測量。此外，在這種情況下，自相關器仍保持自由空間測量能力。
應用：
● 飛秒振蕩器的脈沖持續(xù)時間的測量
