一.什么是光腔衰蕩光譜
1.光腔（optical cavity）
光腔又稱(chēng)為光學(xué)諧振（頻率一致而產(chǎn)生幅值增強(qiáng)的現(xiàn)象）腔。其通常由兩面反射鏡形成的一個(gè)光學(xué)腔體結(jié)構(gòu)。在光腔衰蕩光譜法中，兩面反射鏡都為高反鏡，一面為參考鏡，另一面為被測(cè)鏡。光波會(huì)限制在腔體內(nèi)產(chǎn)生多次反射。
2.光腔衰蕩（cavity ring-down/CRD）
一束光照射進(jìn)由參考鏡和被測(cè)鏡組成的光腔中，光會(huì)在光腔中多次反射。由于反射鏡并不是百分百反射，有透射和吸收等損耗的影響。光的能量會(huì)隨時(shí)間進(jìn)行一個(gè)衰減。這個(gè)過(guò)程就叫光腔衰蕩。
3.光腔衰蕩光譜（cavity ring-down spectroscopy/CRDS）
光腔衰蕩光譜是一種高靈敏度的光譜技術(shù)，可以通過(guò)光的總損耗來(lái)精確地確定反射鏡的反射率。光腔衰蕩光譜又被稱(chēng)為光腔衰蕩激光吸收光譜（CRLAS）。
光腔衰蕩光譜一般分為脈沖光腔衰蕩光譜和連續(xù)波光腔衰蕩光譜。
二.什么是光譜儀
光譜儀（spectrometer）是一種科學(xué)儀器，用于分離和測(cè)量物理現(xiàn)象的光譜分量。其所測(cè)量的變量通常是光的強(qiáng)度，但也可以是例如偏振狀態(tài)。光譜儀主要由光源、色散組件（棱鏡或光柵）和探測(cè)器組成。用光電探測(cè)器接收色散信號(hào)的光譜儀同時(shí)被稱(chēng)為分光光度計(jì)。
對(duì)于一般光學(xué)元件的反射率測(cè)量中，常用商用光譜儀直接測(cè)量反射光譜，測(cè)量精確度往往依賴(lài)于儀器本身的精確度。
三.光腔衰蕩光譜的設(shè)備是什么？
光腔衰蕩光譜測(cè)量所使用的設(shè)備被稱(chēng)為光腔衰蕩光譜儀。
光腔衰蕩光譜儀與一般光譜儀有一些區(qū)別，其包含一個(gè)用于高精細(xì)度光腔的激光光源、構(gòu)成光腔的兩面高反鏡和探測(cè)器。
光腔衰蕩光譜儀測(cè)量的是，光強(qiáng)衰減為初始強(qiáng)度的 1/e 所需要的時(shí)間，這個(gè)時(shí)間被稱(chēng)為“衰蕩時(shí)間”可以被用來(lái)計(jì)算系統(tǒng)的總損耗。
四.光腔衰蕩光譜的測(cè)試方法是什么？
- 將光腔的兩面鏡子分別設(shè)置為參考鏡和被測(cè)鏡；
- 將激光器的激光（脈沖/連續(xù)）引入光腔，通過(guò)反射鏡的反射，往返光線因多次相長(zhǎng)干涉（頻率相同、振動(dòng)方向相同、相位差恒定的光的疊加增強(qiáng)）迅速增強(qiáng)；
- 之后將激光迅速切斷，使用放置于反射鏡后的探測(cè)器探測(cè)從腔中逸出光強(qiáng)的衰減程度；
- 通過(guò)衰蕩時(shí)間來(lái)計(jì)算相應(yīng)的激光往返一次的總損耗；
- 更改參考反射鏡多次測(cè)量，確認(rèn)被測(cè)反射鏡的損耗，以獲得被測(cè)反射鏡的反射率及其反射光譜。
五.光腔衰蕩光譜的技術(shù)原理是什么
以脈沖光腔衰蕩光譜法做說(shuō)明。脈沖光被限制在空的光腔中做多次反射，因吸收和散射造成光束能量的衰減，其總損耗已被證明為與時(shí)間相關(guān)的指數(shù)函數(shù)。
I(t)=I0e-t/τ
在上式中，I(t)為在t時(shí)刻的光強(qiáng)；I0為初始光強(qiáng)；t為激光器被切斷的瞬間后光束限制在腔內(nèi)反射的時(shí)間；e為自然常數(shù)，其值約為2.718；τ為衰減時(shí)間常數(shù)，表示為It衰減到I0的1/e所需的時(shí)間，其值取決于腔內(nèi)的反射鏡的損耗和其它的一些光學(xué)損耗如散射等。τ用數(shù)學(xué)式可表示為：
τ=(n/c)*(2L/α)
在上式中，n為腔內(nèi)的折射率，一般情況下為空氣，則n=1；c為真空中的光速，其值為3×108m/s；L為腔體長(zhǎng)度，即兩面反射鏡中心的距離；α為系統(tǒng)往返一次的總損耗（包括兩面反射鏡的透射損耗、吸收損耗和散射等其它光學(xué)損耗），即我們關(guān)心的值。
總損耗包括兩面反射鏡的透射損耗、吸收損耗和散射等其它光學(xué)損耗，若假設(shè)兩面反射鏡的反射率R1=R2=R~1時(shí)，由I(t)=I0(R1R2)(n*2L)/c可確認(rèn)總損耗：
α=-ln(R1R2)≈2(1-R)
但我們還有一種更精確的測(cè)試方式。
假設(shè)有三面反射鏡，M1、M2和M3。M1和M2為參考反射鏡，M3為被測(cè)反射鏡。通過(guò)上述方法我們可以獲得M1和M2的總損耗α12，M2和M3的總損耗α23，M1和M3的總損耗α13。由此可以很簡(jiǎn)單地得出被測(cè)反射鏡的單鏡損耗為：
α3=1/2(α23+α13-α12)
由上式，我們就可以獲得一個(gè)準(zhǔn)確率極高的反射率及反射光譜。
