带有反馈的腔内调制激光器，其输出将出现双稳、多稳特性，因而可用作数字光通信的调制源。
Otherwise, the intracavity modulating laser with feedback device can be used in digital optical communication because of its bistable and multistable out-put.
激光器的腔内调制与腔外调制相比有许多独特的优点，因而可望在未来的宽带光通信中得到应用。
The intracavity modulation of laser have more merit than extracavity modulation, and can be used in future wide - band optical communication.
