摘要
讨论了气体介质的非均匀性对飞秒激光高次谐波产生过程的可能影响 .计算结果表明 ,采用喷阀技术所提供的气体介质的密度梯度和气体原子运动速度的影响很小 ,不会产生实验上可观测的效果 .
The possible influence of nonuniform gaseous medium on high order harmonics generated by femtosecond laser is discussed. The results of the computation indicate that the gradient of the gaseous medium and the velocity of gas atoms from the jet cannot cause detectable effects in experiments.This result supports the widespread use of gas jet in experiments concerning high order harmonics.
