摘要

摘要考虑光脉冲在三次五次非线性介质中的传播，并在变分方法的框架内分析了脉冲压缩的动力学。基于电势模型，求出稳定传播的有效脉宽。我们看到，在三次介质中传播的脉冲由于五次非线性而被压缩。压缩脉冲的宽度随功率的增大而减小。然而，其最小值受到临界功率以上不稳定性增长的限制。我们明确地检验了由于三次非线性和五次非线性的竞争，压缩脉冲是动态稳定的。

Dynamics of Compressed Optical Pulse in Cubic-quintic Media

ABSTRACT We consider optical pulse propagation in cubic-quintic nonlinear media and analyze the dynamics of pulse compression within the framework of variational approach. Based on a potential model we find effective pulse width for stable propagation. We see that a pulse propagating in cubic media gets compressed due to quintic nonlinearity. The value of width of a compressed pulse decreases with the increase of power. However, its minimum value is limited by the growing instability above the critical power. We explicitly examine that the compressed pulse is dynamically stable due to the competition between cubic and quintic nonlinearities.

期刊介绍： Fiber and Integrated Optics , now incorporating the International Journal of Optoelectronics, is an international bimonthly journal that disseminates significant developments and in-depth surveys in the fields of fiber and integrated optics. The journal is unique in bridging the major disciplines relevant to optical fibers and electro-optical devices. This results in a balanced presentation of basic research, systems applications, and economics. For more than a decade, Fiber and Integrated Optics has been a valuable forum for scientists, engineers, manufacturers, and the business community to exchange and discuss techno-economic advances in the field.
