Abstract

The influence to filamentation of femtosecond by atmospheric turbulence at wavelength of 400 nm has been studied numerically. Simulations show that the distance of filamentation at 400 nm is advanced, the number of filaments increases, and the energy of filaments decreases with the addition of turbulent screen. Compared with the filaments formed by the 800 nm femtosecond laser, the nonlinear propagation of 400 nm laser has a longer filamentation distance in the turbulent atmosphere, and the clamping light intensity of the filaments is higher, but the number of filaments has reduced. With the increase of propagation distance, the multifilament structure disappears and the beam gradually converges into a stable monofilament structure. The position of the monofilament structure at 400 nm is closer than the 800 nm. Therefore, stable filament structure can be obtained more easily with a femtosecond laser at 400 nm.
