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。This thesis was divided into eight chapters, and the main results and innovations obtained here can be summarized as follows : ( 1 ) the physics model of tsrs in frequency conversion crystals has been built up firstly. based on quantum - mechanical viewpoints and the following physical processes and parameters : the two - photo interaction of light with matter, paraxial diffraction of stokes, langevin noise sources, reflection at the faces and the edges of crystals, gain coefficient, beam aperture, pulse width and fluence of 3, the physics model of tsrs in kdp and kdp crystals acting as high - fluence frequency convector and the paraxial operator maxwell - bloch - langevin equations have been built up

用亥姆霍茲-基爾霍夫積分定理和基爾霍夫邊界條件，推導出了平面波經小圓孔非傍軸衍射時軸上強度的簡單解析表達式，研究了平面波經小圓孔后整個衍射空間非傍軸的軸上光強分佈.給出了計算圓孔菲涅爾數的精確公式，重新檢查了通常的菲涅爾數公式的有效性.數值計算顯示，應用解析表達式所得的結果與應用衍射積分公式所得的結果完全一致The cold sunlight of this spring evening peered invidiously upon the crocks and kettles, upon the bunches of dried herbs shivering in the breeze, upon the brass handles of the dresser, upon the wicker - cradle they had all been rocked in, and upon the well - rubbed clock - case all of which gave out the reproachful gleam of indoor articles abandoned to the vicissitudes of a roofless exposure for which they were never made
春天傍晚清冷的太陽，好像含有惡意似地照射著那些壇壇罐罐，照射著一叢叢在微風中索索發抖的枯草，照射著碗櫃的銅把手，照射到他們所有的孩子都睡過的那個搖籃上，照射在那座被擦得發亮的鐘面上，太陽照射著所有這一切，這一切閃現著責備的亮光，好像在說，這些室內的物品，怎麼會被扔到露天里來了。The next morn broke off the coast of aleria ; all day they coasted, and in the evening saw fires lighted on land ; the position of these was no doubt a signal for landing, for a ship s lantern was hung up at the mast - head instead of the streamer, and they came to within a gunshot of the shore
他們整天沿著海岸航行，到了傍晚時分，岸上燃起了燈火。這火光大概是約定的暗號，一看到這火光，他們就知道可以靠岸了，因為有一盞信號燈不是掛在旗桿上而是掛在桅頂上，於是他們就向岸邊靠近，駛到了大炮的射程以內。When the weather is fair and settled, they are clothed in blue and purple, and print their bold outlines on the clear evening sky ; but sometimes, when the rest of the landscape is cloudless, they will gather a hood of gray vapors about their summits, which, in the last rays of the setting sum, will glow and light up like a crown of glory
每當天氣持續晴朗的時候，它們就會披上藍紫相間的外衣，把它們那雄偉的輪廓印在傍晚清澄的天空上；有時，雖然山巒的四周晴空萬里，但山頂卻被一團灰霧鎖籠罩，在落日余輝的照耀下，像一頂燦爛的皇冠光芒四射。It is so high in the upper air that when the sun has not risen above the horizon before dawn or has gone downhill after nightfall, sunlight can still shine on this detached, over - hanging and shadowless cloud. after scattering the sunlight, it produces an attractive red or orange hue, a very common sight on summer days
所以清晨當太陽還沒有升到地平線上或傍晚太陽已下山後，光線都會照到這種孤懸高空而無雲影的捲雲上，經過散射后，顯現出漂亮的紅色或橘紅色的霞象，在夏日的晴空中十分常見。Firstly, in the paper a family of integral solution representing ultrashort pulsed beam propagating in free space have been studied by using the co - moving frame coordinates and the fourier transformation for time variable in terms of well - known paraxial approximation. and the pulsed gaussian - like beam solution can be obtained as a especial solution of the integral solution, where including the pulsed gaussian beam
