摘要
暗脉冲激光在光波导中传输噪声小、损耗低,因此在信号处理方面比传统亮脉冲更有优势。介绍了暗脉冲激光器的国内外研究进展,重点介绍了经后期光学或电学整形产生暗脉冲和激光器直接产生暗脉冲的各种理论方案,最后对暗脉冲激光器的应用和发展前景进行了展望,并指出了目前还存在的问题。
Dark pulses propagate with low noise and low loss in optic waveguides,so dark pulses have an advantage over bright pulses in signal processing.Research progress of dark pulse laser is reviewed.Emphases are placed on dark pulse output schemes based on optical shaping or electrical shaping,and dark pulse output directly from a laser cavity.And the applications and prospect related to dark pulse laser are presented.The remaining problems are pointed out.
