Control of multiple filamentation induced by ultrafast laser pulses
摘要
Abstract
The filamentation phenomena come from the propagation of intense ultrafast laser pulses in transparent optical media is explored. It shows that the irregular distribution of filaments will reduce the quality of laser beams, effect on its energy distribution and constitute a serious drawback in practical applications. Therefore, this paper studies how to control the multiple filaments come from higher power laser propagation in optical media and analyzes and compares these control methods. It points out that the amplitude modulation and phase modulation are the main methods to control the multiple filamentation currently, which can decrease or eliminate the intensity perturbance and refractive index perturbance of transmission media, and avoids the interrelation between the multiple filamentations and their energy competition so that the multiple filamentations can be arranged in a preconceived form. It summarized that the existing problems for multiple filamentation control are how to control the length and spacing of the filamentation precisely.关键词
