“…The dynamic equilibrium between the Kerr self-focusing and plasma-defocusing effects leads to filamentation [1][2][3] . Due to its potential applications in supercontinuum emission [4][5][6] , extreme ultraviolet (EUV) emission [7,8] , air lasing [9,10] , THz radiation [11,12] , remote sensing [13] , guiding of corona discharges [14] , machining [15] and weather control [16] , filamentation of femtosecond laser pulses in optically transparent media has attracted a great deal of attention in recent years. One of the most profound effects during femtosecond filamentation is intensity clamping phenomena.…”
