摘要 为了寻找理想的光纤低损耗区进行光孤子通信的孤子源,根据脉冲在Cr4+∶YAG激光器里传播特性获得了带微扰的非线性薛定谔方程,系统分析了腔内色散、增益、损耗、非线性效应等对基态孤子脉冲的影响以及Cr4+∶YAG激光器腔结构与锁模基态孤子脉冲参数的相互关系,证明在Cr4+∶YAG激光器中能够产生基态孤子脉冲,Cr4+∶YAG激光器可作为光孤子通信系统的孤子源。 The soliton source is the key element in the soliton communication system. In order to search the satisfying soliton souse in the low loss fiber of the soliton communication, the disturbed nonlinear Sehroedinger equation of the ultrashort optical pulses was derived in response to the property of pulse in the Cr^4+:YAG laser,the influence of dispersion and gain and loss and nonlinear effect on the fundamental soliton was analysed in the cavity in system, the relation between the configuration of the cavity and the parameters of the fundamental soliton was discussed,It is proved that the generation of the fundamental soliton in the Cr^4+: YAG laser,and the Cr^4+:YAG laser may be the soliton source of the soliton communication system。
