摘要
本文分析了NAB[NdAl_3(BO_3)_4]自激活激光晶体脉冲被动锁模的优越性。研究了对撞增强自起动自泵浦近简并四波混频相位共轭腔的形成条件及其在锁模过程中的作用。首次演示了NAB对撞增增强快速压缩脉冲锁模过程。获得了平均7ps的超短脉冲的实验结果。
The excellent passivly pulse mode-locking performances of the NAB[NdAl3(BO3)4] laser crystal are analyzed. The formation conditions of the self-starting and self-pumped degenerate four-wave mixing-phaseconjugate resonator (DFWM-PCR)and it is function in quickly mode-locking process are stadied. For the first time, demonstration of NAB collisionally enhanced quickly compression process of the mode-locking pulse width is performed experimentally. The result of 7 ps ultrashort pulse has been obtained.
