Advances in mechanism research of femtosecond laser filamentation induced hydrometeors formation

In recent years, various nonlinear effects associated with femtosecond laser filamentation and their potential applications had become one of the important research directions in the field of ultrashort and ultraintense pulsed laser technology. Femtosecond laser filamentation-induced condensation of water vopor, snowfall and secondary ice multiplication opened up new perspective for weather modification,which was of great scientific significance and application prospects. Firstly, the research progress of the basic observation and mechanism of laser-induced hydrometeors were analyzed. Then, challenges in the mechanism research of femtosecond laser filamentation-induced hydrometeors had been discussed and prospects of the development direction of the active utilization of intense laser atmospheric effects were also summarized.
