超短脈沖測量儀Frog（擴展掃描范圍）
IRA超短脈沖測量儀Frog（擴展掃描范圍）是專門為測量超快放大器和振蕩器產(chǎn)生的超快輻射脈沖寬度和近對比度而開發(fā)的。還有一種特殊的IRA系統(tǒng)模型，適用于中紅外激光源。IRA包括光學(xué)機械組件和電子設(shè)備與USB接口。系統(tǒng)易于操作，并包括一套完整的數(shù)據(jù)收集和分析用戶友好的軟件工具。逼近Gaussian和Sech2線性的也可以。光學(xué)機械組件由參考脈沖的額外延遲光學(xué)箱和機械套件組成。
采集和分析軟件與Windows XP*兼容，USB驅(qū)動程序都包括在內(nèi)。
特點：
● 脈沖寬度范圍50fs - 250 ps
● 波長范圍450nm-11 µm
● USB連接和軟件
應(yīng)用：
● 飛秒和皮秒OPA脈沖持續(xù)時間和附近測量對比
