用电容器模型计算了激光打靶过程中由共振吸收诱发的高次谐波，并在此基础上讨论了超短脉冲强激光的高次谐波作为一种短波长相干辐射源的可能性。 The capacitor model was used to calculate the higher harmonics induced by resonance absorption in the process of laser targeting. On the basis of this, the possibility of higher harmonics of ultrashort pulsed laser as a short wavelength coherent radiation source was discussed.
