  • Working on laser diode fiber - coupling modules was summed up , they are , setting up the model of far - field distribution of laser array and the far - field characteristics of difference structures ; designing the temperature - controlled laser diode fiber modules , that has been used as a laser system with temperature - controlled and fiber - output ; realization with high - brightness laser diode fiber - coupling modules ; the fiber ' s application in the field of high power laser
    總結(jié)了自己在光纖耦合輸出激光二極管模塊方面所做的一些工作，建立了半導(dǎo)體激光器列陣遠(yuǎn)場(chǎng)光束分布模型，并結(jié)合具體參數(shù)分析了不同結(jié)構(gòu)的激光器列陣的光束遠(yuǎn)場(chǎng)分布特性，可以知道我們?cè)O(shè)計(jì)和優(yōu)化激光器列陣的結(jié)構(gòu)。設(shè)計(jì)并制作了光纖耦合模塊的溫度控制系統(tǒng)，并制作成溫控光纖輸出激光器半導(dǎo)體系統(tǒng)投入使用。
  • On the other hand , the electric field and intensity distributions of the he11 mode in the hollow fiber are calculated by using the exact solutions of maxwell equations based on the vector model , and the diffracted near - and far - field distributions of the he11 - mode output beam under the fresnel approximation are studies . we derive an analytical expression on the far - field distribution of the he n - mode output beam in free space and discuss its applicable condition . we also analyze and compare the differences between the he11 - and lp01 - mode output beams , and find that the near - field distribution of the lpoi - mode output beam is a gaussian - like one , but the near - field distribution of the he11 - mode output beam is a doughnut - like one , whereas the far - field distribution of both the lp01 - and he11 - mode output beams are a doughnut one
    此外，我們把中空光纖中l(wèi)p _ ( 01 )模(標(biāo)量模型)和he _ ( 11 )模(矢量模型)的場(chǎng)分布以及它們各自的輸出光束的近場(chǎng)與遠(yuǎn)場(chǎng)分布進(jìn)行了比較，發(fā)現(xiàn)兩種模式的輸出光束在近場(chǎng)分布有很大的區(qū)別， lp _ ( 01 )模輸出光束在近場(chǎng)是一個(gè)高斯分布，而he _ ( 11 )模輸出光束在近場(chǎng)是一個(gè)中空光束，在遠(yuǎn)場(chǎng)兩種模式的輸出光束分布是基本一致的，這正是由于在中空光纖中采用了弱波導(dǎo)近似以后所引起的誤差。
  • In addition , this paper has analyzed and calculated the wave - guide mode theory , got the quantum well laser photic - field distribution ' s fluctuation equation , deduced the far - field distribution ' s mathematics model by the method of stepwise approached , and simulated the near - field and far - field about the laser with computer software . we utilized a pair of mode expand layers which can restricted in photic - field to narrowed the far - field comer about quantum well laser material structure ( the corner was about 21 ?
    另外本文還對(duì)光波導(dǎo)模式理論進(jìn)行了理論分析和計(jì)算，得到了量子阱激光器光場(chǎng)分布的波動(dòng)方程，利用逐步逼近的方法推導(dǎo)出了遠(yuǎn)場(chǎng)分布的數(shù)值模型，通過(guò)計(jì)算機(jī)軟件模擬出了激光器遠(yuǎn)近場(chǎng)分布圖，并利用模式擴(kuò)展層對(duì)光場(chǎng)的限制作用得到了窄遠(yuǎn)場(chǎng)發(fā)散角(約為21 )的量子阱激光器材料結(jié)構(gòu)。
