| 摘 要： | Cr4+:YAG晶体具有独特的增益特性和非线性特性，从Cr4+:YAG激光器的传播方程出发讨论了晶体的非线性效应对激光脉冲的影响，由于激光晶体的非线性效应Cr4+∶YAG激光器可以在不存在其他锁模器件情形下自锁模，并使激光脉冲出现频率啁啾，在激光器腔内进行色散补偿并使色散与非线性效应达到平衡时腔内可形成孤子脉冲，成为一种孤子源。

| Abstract: | It is the unique gain and nonlinear attribute of the Cr4+:YAG crystal,the influence to pulse is discussed by the crystal nonlinear effect from the propagation equation in the Cr4+:YAG laser.It is possible that self mode locked without other mode locked device for the crystal nonlinear effect and the pulse frequency chirp by the crystal nonlinear effect,the soliton pulse is generated in the balance between dispersion and nonlinear effect by dispersion compensation in the cavity,it is one of soliton light source. |
