IRA中紅外掃描式自相關儀
步進電機驅(qū)動的長延遲線掃描自相關器適用于描述飛秒和皮秒激光源的特性，包括從可見光到MIR的各種輸入脈沖參數(shù)和波長的組合。
IRA掃描自相關器是專門為測量超快放大器和振蕩器產(chǎn)生的超快輻射的脈沖持續(xù)時間和近對比度而研制的。此外，還有一種特殊的IRA系統(tǒng)模型，適用于中紅外激光光源。
IRA包括光學機械裝配和帶有USB接口的電子產(chǎn)品。該系統(tǒng)操作簡單，包括一套完整的用戶友好的Windows軟件工具，用于數(shù)據(jù)收集和分析。高斯和Sech^2形狀的近似也是可用的。該單元實現(xiàn)了健壯的掃描機制。
采集和分析軟件兼容Windows，包括USB驅(qū)動程序
