Abstract

The potential of hollow core photonic crystal fiber as a nonlinear gas cell for efficient high harmonic generation is discussed. The feasibility of phase-matching this process by modulating the phase of ionization electrons using a counter-propagating laser field is shown. In this way, harmonics with energies of several hundreds of eV can be produced using fs-laser pump pulses of microJ energy.

摘要

讨论了空心光子晶体光纤作为用于高效高次谐波产生的非线性气室的潜力。展示了通过使用反向传播激光场调制电离电子的相位来实现该过程相位匹配的可行性。通过这种方式，使用微焦耳能量的飞秒激光泵浦脉冲可以产生能量为数百电子伏特的谐波。
