摘　　要：本文叙述了群速弥散补偿被动锁模环型染料激光器的特性;研究了产生极短飞秒光脉冲的条件和光脉冲强度分布的非对称性。该技术产生的最短光脉冲宽度为21 fs;光脉冲宽度可调范围从最短到500fs以上。实验和理论数据拟合证明光强分布为非对称双曲正割平方,非对称因子r在7到11之间。This paper describes the characteristics of group velocity dispersion compensated passively modelocked ring dye laser; investigated the conditions of generating ultrashort femtosecond light pulses, and pulse asymmetry. The pulse durations as short as 21 fem-tosecond have been obtained with this technique. The widths of laser pulses can be adjusted from the shortest one to more than 500 fs. Fitting of e experimental and theo-retical data has shown that the intensity profites of light pulses are asymmetric sech2. The factors of asymmetry are between 7 and 11.
