diffraction loss中文什么意思
例句與用法
- The former has compact structure ; , little cavity loss , higher coupling efficiency , and higher superposition efficiency . but there is no enough room for other devices . the latter overcome this problem , but the diffraction loss and mirror loss is increased
六鏡環(huán)形諧振腔可以確保角度很小，但總腔長(zhǎng)較長(zhǎng)，腔內(nèi)衍射及腔鏡吸收和不完全反射造成的損耗較大，同樣很難得到穩(wěn)定的雙波長(zhǎng)激光輸出。 - Used as ring - down cavity , this stable resonator has , firstly , more influence of misalignment of cavity mirrors on its measured reflectivity , but less of length misadjustment ; secondly , shorter cavity length which advantageous in engineering ; finally , less diffraction loss and thus higher metrical precision
結(jié)果表明，這種穩(wěn)定腔用作衰蕩腔，測(cè)量結(jié)果受腔鏡角度失調(diào)影響較大，而受腔長(zhǎng)失調(diào)影響?。黄溟L(zhǎng)度較短，便于工程應(yīng)用；衍射損耗較小，測(cè)量精度高。 - According to the theory of acousto - optic ( ao ) interaction , the formulas of diffraction loss of two ao q - switches , which acousto - field are perpendicular or parallel one another , the power divider for ensuring two ao q - switch synchronization and effective power driving is designed . the calculation results are satisfied with nd : yag laser experimental results . it is show that two ao q - switches , which acousto - field are perpendicular each other , switch - loss is nearly one times larger than one ao q - switch , one of third larger than the two ao q - switches which acousto - field are parallel
從理論上對(duì)聲光器件衍射損耗作了分析與計(jì)算，研究了二維雙聲光器件對(duì)提高衍射損耗效率的影響，在實(shí)驗(yàn)中采用二維雙聲光組合器件提高聲光器件的對(duì)nd ： yag激光器的關(guān)斷能力，較之單聲光的關(guān)斷能力提高了一倍左右，而對(duì)于平行雙聲光也提高了30左右，并設(shè)計(jì)了聲光驅(qū)動(dòng)功率分配器以驅(qū)動(dòng)雙聲光器件達(dá)到同步，消除了激光輸出的多脈沖現(xiàn)象，提高了脈沖列的輸出功率。 - Three parts ( 6 chapters ) are included in this dissertation except the 1 st and 6th chapters . the first part ( the 2nd , 3rd and 4th chapters ) is the theory for analyzing and designing resonators with diffraction optical elements by use of a matrix eigenvalue method . the eigen modes and diffraction loss for a laser cavity have been obtained by this method
本論文主要包括三個(gè)部分共八章，除第一章緒論和第八章總結(jié)外，主要內(nèi)容如下：第一部分(第二、三、四章)主要討論和分析了決定激光光束的輸出特性和光束參量的激光諧振腔，闡述和建立了矩陣本征值方法分析和設(shè)計(jì)激光諧振腔的系統(tǒng)理論。
