STUDY ON FILAMENTATION IN FEMTOSECOND LASER PLASMAS
|
Abstract:
The local density fluctuation in femtosecond laser plasmas has been studied using optical shadowgraphy and scattering imaging techniques.The instability of filamentation in the laser plasma has been observed,and the local density fluctuation studied.The result shows that this instability of filamentation is caused by the ponderomotive force.
