AA-20DD自相關(guān)儀
AA-20DD實(shí)時自相關(guān)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(guān)器可以通過使用最多4個可互換的光電檢測器和光學(xué)器件包括一些波長范圍。兩個獨(dú)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(guān)）。
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(shè)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(shí)時自相關(guān)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(xiàng)被啟用，強(qiáng)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(jìn)行比較。
對AA-20DD的微小的身體地適用于任何實(shí)驗(yàn)設(shè)備與嚴(yán)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(guān)器仍保持自由空間測量能力。
