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)場分布特性，可以知道我們設(shè)計和優(yōu)化激光器列陣的結(jié)構(gòu)。設(shè)計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)的場分布以及它們各自的輸出光束的近場與遠(yuǎn)場分布進(jìn)行了比較，發(fā)現(xiàn)兩種模式的輸出光束在近場分布有很大的區(qū)別， lp _ ( 01 )模輸出光束在近場是一個高斯分布，而he _ ( 11 )模輸出光束在近場是一個中空光束，在遠(yuǎn)場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。
