ANALYTICAL EXPRESSION OF SECOND-ORDER AND THIRD ORDER DISPERSIONS IN THREE-ELEMENT RESONATOR USED FOR KERR LENS MODE-LOCKING 

给出在任意角度切割情况下 ,三元腔固体自锁模激光器二阶、三阶色散的解析表示 ,并系统地计算了切割角度、材料等因素的变化对二阶、三阶色散的影响 .该计算为三元腔固体自锁模激光器的设计提供了理论依据 .

In this paper,we give an analytical expression of second-and third-order dispersions for three-element cavity. The variations of the second- and third-order diapersions owing to the changing of Ti:Al2O3 crystal and prismatic output coupler are calculated. The results provide a theoretical basis for the design of three-element cavity.
