华中科技大学博士学位论文 和调Q饱和光强相差为5个数量级.对各种腔长时激光器的被动锁模特性进行了详细 研究。平凹腔腔长为68cm时,泵浦功率为4W,锁模调制深度达到80 ,锁模脉宽 约800ps,此时腔内光强仅为6x10*W/cm。在各种腔长实验中,得到锁模调制深度从 50 到80 ,腔长在一定区域内有最佳锁模稳定度.Nd:YAG946nm激光器倍频得到473nm波长的蓝光激光器,是目前获得全固态蓝 光激光器最有效的途径之一。在理论分析准三能级激光器系统的基础上,详细研究了 946nmNd:YAG激光器的特性,针对它阈值高和有重吸收的特点设计激光器。
华中科技大学博士学位论文 is difficult to use Cr:YAG as a saturable absorber forNd:YVO4 laser.However, it was found that theintracavity saturationintensity ofco-dopedNd,Cr:YAGcrystalwasmuch lower than Cr:YAG,which resolves this problem.Diode pumped passively Q-switched Nd:YVO1.
