In chapter 2, a schrodinger formulation for paraxial light beam propagation of the real and comprehensive refractive indexes is represented. the equation for the atom laser beam wave - function is also given by a schrodinger equation, which is similar to the equation of the time - dependent system. therefore, it is possible to investigate the propagation of an atom laser beam
第二章:本章介紹了傍軸光束在實數折射率介質和復數折射率介質中傳輸的schrdinger形式理論,同時指出由於原子激光的傳輸滿足schrdinger方程,與含時量子系統的傳輸方程類似,故利用含時量子系統的schrdinger形式理論來研究原子激光的傳輸是可行的。Various factors affecting the refractive index and the deposition rate of the deposited films are studied to optimize growth conditions of the films. the microstructures and optical properties of the films are characterized by a prism coupler, a fourier transform infrared spectroscopy ( ftir ) and an atom force microscopy ( afm )
研究了薄膜折射率和淀積速率與工藝參數之間的關系,通過棱鏡耦合儀、傅立葉變換紅外光譜、原子力顯微鏡、掃描電子顯微鏡等測試手段,分析了薄膜的結構和光學特性。In this paper we have predicted two kinds of new quantum coherence effects. one is the strong - field index enhancement via selective population trapping of dressed states and the other is the preservation of the coherent population trapping ( cpt ) is by quantum interference of incoherent pump processes
本文提出了兩類新的原子相干效應,一是利用選擇性修飾態捕獲產生強場折射率增強,二是非相干泵浦誘導的量子干涉保護相干捕獲。This kind of coherent trapping leads maximal atomic coherence, which characterizes ultralarge index of refraction and vanishing absorption
這樣的相干捕獲導致最大的原子相干,就對應超大折射率和消失的吸收。The relationship between sputtering conditions and the depositional speed shows : with working pressure 1. 2 pa, sputtering power 180w, the depositional speed of tio2 thin film is 40nm / h, and increases with the increasing of sputtering power. it can be also founded that the depositional speed is nearly proportional to the working pressure : within the range of 0. 3pa to 1. 6pa, the depositional speed increases linearly with the increase of ar pressure. with the enhancement of the substrate ' s temperature of sputtering or annealing, the resulted thin films show a tendency of decreasing in thickness, and increasing in refractivity
本實驗是採用磁控濺射方法,在不同的溫度下制備了tio _ 2薄膜,並對薄膜進行了不同溫度和時間的退火處理,通過原子力顯微鏡( afm ) 、 x射線衍射( xrd ) 、掃描電鏡( sem )等檢測手段對薄膜的表面形貌和組成結構進行了分析,結果如下: ( 1 )濺射工藝條件與薄膜沉積速度的關系表明:採用1 . 2pa工作氣壓, 180w的射頻功率tio _ 2薄膜的沉積速率為40nm h ,並隨射頻功率的增加而提高,呈近似的線性關系,在0 . 3pa 1 . 6pa氣壓范圍中,氬氣壓強升高沉積速率迅速增加,濺射溫度提高和退火處理能使薄膜的厚度減小和折射率提高。Recent studies have shown that the quantum coherent population trapping, electromagnetically induced transparency, index enhancement without absorption, etc. these new effects have great potential for the control of the coherence properties of a medium, the production of high frequency lasers, the information storage and high precision measurements
最近的研究表明,原子相干產生很多新的效應,如相干布居捕獲、無反轉激光、折射率增強、電磁誘導透明、電磁誘導吸收等。這些新效應對光學介質相干性質的控制、高頻激光的產生、光信息存儲和高度測量等方面具有巨大的應用前景。Recent studies have shown that the quantum coherence and interference have led to a lot of new effects such as coherent population trapping, electromagnetically induced transparency, index enhancement without absorption, etc. these new effects have great potential for the control of the coherence properties of a medium, the production of high frequency lasers, the information storage and high precision measurements

根據對其倍頻原理及性能的分析討論,在用該晶體完成波長從858nm到429nm的二階非線性轉換時,採用非臨界相位匹配條件(此時無離散效應,對應的雙折射參數b = 0 ,共焦長度為= 2 . 84 ,最佳相位失配因子為= 0 . 574 ) ,在相位匹配溫度約為23 . 5時,理論上通過計算得到理想情況下非線性轉換系數約為1 . 45 / w (長度為7mm ) , 2 . 07 / w (長度為10mm ) 。Three characteristic features are found. first, for the same set of atom - light interaction parameters, the indices of refraction are large at three different frequencies where the absorption vanishes. these three frequencies are determined by the resonance transition frequencies between dressed states produced by the strong driving field
我們發現了三個重要特徵:首先,在相同的原子和光相互作用參數條件下,同時存在三個無吸收折射率增強點,這三個點所處的頻率位置由驅動場產生的修飾態之間的共振躍遷決定。When we were discussing the index of refraction, we saw that an incoming beam of light will make the atoms radiate again.
在討論折射率時,我們曾看到入射光束使原子再輻射。The microstructures and physics properties of the sbn films were characterized by xrd, afm, sims, raman scattering, and spectrophotometer, electrical induced birefringence etc. the effects of growth parameters on the quality of sbn films were discussed, such as substrates, annealing temperature, and precursor solution, bufferlayer ( ksbn, mgo )
