The factors that influenced the output of the laser were analyzed theoretically . the output power of the laser was observed to be related with the length of eof , the coupled - ration of the output coupler and the loss of splicing 并在摻鉺光纖激光器理論分析基礎(chǔ)上,討論了影響激光器輸出的各種因素:腔長、輸出耦合比、諧振腔損耗。且作了相應(yīng)的實驗,與理論結(jié)果相一致。
Based on an amplified spontaneous emission ( ase ) source , a ring - cavity fiber laser , in which sensor element acted as the reflector of the cavity , was achieved with high - signal noise ratio ( snr ) and high - power . it was demonstrated that the output power was maximum , when output coupler ratio of the coupler was seventy percent 實驗證實耦合器的輸出耦合比選為某一個最佳值70 ,當980nm泵光工作電流為50ma時,其輸出功率達3 . 5mw ,且輸出激光波長與作為反射鏡的光纖光柵中心波長相同。
