摘要
构建了基于分布反馈式(DFB)光纤激光器的光纤激光水听器阵列,4元DFB光纤激光器通过同一个980nm激光器同线泵浦,阵列发出的1550nm左右的复合激光通过解波分复用(BWDM)分离至独立的通道,实验结果表明,4元光纤激光水听器探测的水声信号能被无失真的解调,阵列各通道间串扰小于-60dB。
A fiber optic hydrophone array based on distributed feed-back(DFB) fiber lasers is presented. Four DFB lasers are pumped by a 980 ran laser, and the reflected light at 1550 nm is wavelength-division demultiplexed. Experimental results show that the acoustic signals in the four channels are correctly re- trieved,and a crosstalk better than 60 dB is achieved.
