Abstract

摘要: 构建了被动锁模光纤激光器的理论模型，通过数值仿真从时域和频域两个方面研究了高阶色散对输出脉冲特性的影响，在时域方面，三阶色散导致脉冲形状发生畸变，脉冲时域轮廓不对称，时域偏移等现象；在频域方面，三阶色散导致边带位置及强度发生变化。同时，研究发现四阶色散可以展宽脉冲，改变脉冲的边带强度。本文的研究结果对被动锁模掺镱光纤激光器的实际应用具有指导意义。关键词: 激光器 / 被动锁模激光器 / 三阶色散 / 四阶色散

期刊介绍： Journal of Applied Optics was founded in 1980, and its domestic and international publication numbers are ISSN 1002-2082 and CN-61-1171/O4. The journal is a technical journal sponsored by the China Ordnance Society and the 205th Institute of China Ordnance Industry. It was included in the "China Science and Technology Core Journal" in April 2006 and in the "Chinese Core Journal" in December 2008. It is included in the journals of important international retrieval institutions such as the American Chemical Abstracts (CA), Cambridge Scientific Abstracts (CSA), Russian Abstracts Journal (AJ), British Scientific Abstracts (INSPEC), Ulrich's Periodical Directory (UIPD), and Polish Index Copernicus (IC). The purpose of the journal is to track the research trends of high-tech at home and abroad, and comprehensively reflect the development status, research level, and application of optoelectronic technology at home and abroad; focus on optoelectronic application technology, advocate scientific research, be close to readers, and be close to enterprises, and focus on reporting new theories, new technologies and new methods, new products, and development trends in the field of optoelectronic technology at home and abroad. This journal solicits research papers on engineering optics, optical information acquisition and processing, optical metrology and detection, low-light-level night vision technology, fiber optic sensing technology, infrared application technology, laser application technology, optoelectronic devices, thin film optics, optical processes and equipment, and displays.
