| 2. | In recent years , fiber lasers have developed rapidly due to the demand of optical fiber communication , especially , the ultra - short pulse fiber laser which has drawn more and more attention because of its potential applications in otdm ( optical time division multiplexing ) technique and optical soliton communication system 近年来,由于光纤通信的发展需要,光纤激光器得到了迅猛的发展,特别是短脉冲光纤激光器,由于在光时分复用( otdm )技术和光孤子通信系统中的潜在应用,更是受到了越来越多的关注。 |
