| 摘 要： | Nd:LMA晶体相对低的非线性折射率n2,使得针对Ti:Sapphire自锁模激光器设计的腔,对Nd:LMA介质而言并没有提供足够的自幅度调制(SAM).为了在Nd:LMA激光器上实现自锁模,在腔内引入一个具有大的非线性系数n2、快的响应时间的SF57介质,这样就使得激光腔的结构比较特殊.在这篇文章里利用ABCD传输矩阵对该激光器的结构从理论上进行了分析和计算,使腔结构达到了最佳化设计.

| Abstract: | The cavity design for Ti:Sapphire Kerr-lens mode locked laser can not provide enough self amplitude modulated (SAM) because of small nonliner coefficient of Nd:LMA laser crystal.The additional Kerr medium (SF57),with large nonliner coefficient and fast response time,was put into laser cavity inside so as to do Kerr-lens mode locked on Nd:LMA laser,which has special cavity structure.In this paper the cavity structure was analysized and designed by using ABCD matrix formula to get optimize. |
