The distribution and evolution of filamentation of femtosecond laser pulses with the chessboard-like and grid-like phase plates, respectively, in air are numerically studied. It is demonstrated that the filamentation can be controlled by using the two phase plates. More clearly separated and more stable filaments are formed by using the chessboard-like phase plate, while longer filaments are formed by using the grid-like phase plate.
