為減少打標畸變，採用垂直二維振鏡分佈， f物鏡聚焦，將激光束經第二個振鏡反射後到加工平面的距離為焦距f ，為了避免打標時間過長，溫度過高破壞諧振腔，在設計中加上冷卻系統和自我保護裝置。It has been shown that when the partially coherent beams propagate in the atmosphere, it may be less affected by turbulence than are fully coherent ones. moreover in laser fusion a highly coherent beam is transformed into a partially coherent beam, for reducing the speckle and for getting more smooth focused spot
例如，部分相干光在大氣中傳輸時所受大氣騷動的影響要比完全相干光小得多;並且部分相干光束具有光強比較均勻，對散斑低靈敏等優點而被應用於激光核聚變等領域。This is due to the fact that laser beams with a flat - top profile or other kinds of profiles are desired in various applications, such as in the applications of laser fusion, laser heat treatment and optical data processing etc. nevertheless most of study on the beam shaping is concentrated on the beam shaping of spatially completely coherent beams
光束整形之所以熱門，是因為這些特殊形式的光束可應用於激光光學及生物醫學等領域。例如，平頂光束可應用於激光核聚變、激光熱處理等領域。然而，研究者對部分相干光的光束整形的研究還很少。3. introduced the principle of phase - match and the optics characters of ktp 、 lbo and other nonliner crystrals, demonstrate the optimal focusing conditions. based on a detailed analysis, ktp and lbo are selected as shg and thg cystal, respectively
3 .簡單介紹相位匹配原理和非線性晶體的選擇介紹了一些紫外晶體的光學特性，並闡述了光束的最佳聚焦條件，經過分析和綜合評價，選擇了ktp和lbo分別作為倍頻晶體及和頻晶體。Paper and board - measurement of specular gloss - 75 gloss with a converging beam, tappi method

通過類比的方法給出了一般情況下，同時考慮走離效應和自聚焦效應時的高斯光束倍頻轉換效率公式。4, single focuse the single head : is single for single laser head that panasonic lead off to adopt to focuse the double the laser beam for focusing ordering the project, he adopting the special whole synthesizing lens, passing lens in the center part ofly the focusing of formation cd the point, and pass the anastigmatic laser beam of part edge the formation the focusing of dvd the point, this kind of construction because of have no the machining to spread to move, and also can t produce the mechanical trouble, therefore increased to recognize the dish the speed, and however and also lowered the cost. but adoption this project of generation is with part of the next generation dvd nonsupports cdr
4單聚焦單鏡頭：為panasonic率先採用的單激光頭單聚焦鏡雙聚焦點方案，他採用特別的全息綜合透鏡，通過透鏡中間部分的激光束形成cd的聚焦點，通過透鏡邊緣部分的激光束形成dvd的聚焦點，這種結構由於沒有機械傳動，也不會產生機械故障，所以提高了認盤速度，不過同時也降低了成本。但採用此方案的第一代和部分第二代dvd不支持cdr 。Beam angles of spotlights
聚光燈光束角度Early in the morning of october 15, 1997, standing in the dark on the edge of an alligator - infested inlet near cape canaveral, fla., i watched with thousands of others as a tiny flame appeared beneath a rocket illuminated by floodlights on a launchpad several miles away
1997年10月15日清晨，天色猶暗，我站在美國弗羅里達州卡那維爾角附近一個鱷魚群居的海口邊緣，和好幾千人一起看著數英裡外的發射臺上，被聚光燈照亮的火箭下射出一束細小的火焰。The super resolution effect of sb layer super resolution structure is also investigated with near - field scanning optical microscope. in addition, a rigorous three - dimensional ( 3d ) optical electromagnetic finite - difference time - domain ( fdtd ) model for analysis of a sil system is detailed. in order to accurately analyse sil model, a new method of setting a focused gaussian beam source in fdtd grids is presented
