飛秒激光時(shí)域熱反射測(cè)量技術(shù)，即Time-domain Thermoreflectance, TDTR 是一種基于飛秒超快激光抽運(yùn)探測(cè)（pump-probe）技術(shù)的導(dǎo)熱測(cè)量技術(shù)。相比于其他導(dǎo)熱測(cè)量技術(shù)，目前TDTR技術(shù)因其可以測(cè)量納米薄膜熱導(dǎo)率和界面熱阻以及非接觸式測(cè)量特性而具有獨(dú)特優(yōu)勢(shì)。

?

我司新推出的時(shí)域熱反射測(cè)量系統(tǒng)可用于測(cè)量金屬薄膜、塊體或液體的熱導(dǎo)率、界面熱阻等多項(xiàng)熱物性參數(shù)，薄膜測(cè)量厚度可達(dá)納米量級(jí)！在微納結(jié)構(gòu)新材料的研發(fā)與分析等方面得以越來越廣泛的應(yīng)用。   

系統(tǒng)通過利用飛秒激光照射樣品表層金屬薄膜，令薄膜吸收能量并將其轉(zhuǎn)化為熱能， 從而傳導(dǎo)給樣品，并隨時(shí)間尺度逐漸向樣品傳遞。金屬薄膜表面溫度隨時(shí)間回落，從而影響到其反射率。屆時(shí)再通過測(cè)量另一束探測(cè)激光的反射強(qiáng)度曲線，通過后續(xù)一系列的解調(diào)分析，即可得到金屬薄膜溫度隨時(shí)間的變化，進(jìn)而獲得被測(cè)樣品的導(dǎo)熱特性和相關(guān)熱物性參數(shù)等。

產(chǎn)品特點(diǎn)：

• 超快動(dòng)態(tài)測(cè)量過程，nm級(jí)厚度樣品測(cè)量

• 各項(xiàng)異性熱導(dǎo)率測(cè)量

• 高溫高壓外場(chǎng)測(cè)量（Gpa 高壓環(huán)境  1000℃ 外場(chǎng)環(huán)境兼容）

本系統(tǒng)采用了長(zhǎng)行程線性位移臺(tái)，可以實(shí)現(xiàn)較高時(shí)間分辨率的熱響應(yīng)測(cè)量；

雙波長(zhǎng)激光分別進(jìn)行泵浦和探測(cè)，降低了加熱和探測(cè)過程之間的干擾；

調(diào)制和鎖相的使用進(jìn)一步保證了微小熱響應(yīng)信號(hào)的捕捉和測(cè)量；

ccd顯微可視技術(shù)則能夠精確控制具有微觀結(jié)構(gòu)樣品的測(cè)量。
