Аннотация:We present the results obtained using a new experimental setup for long multiple andsuperfilaments studies. The filaments were formed on atmospheric path with the lengthabout 50 m and the setup permits us to work with laser pulses with energy up to 50 mJ. Weperformed measurements at many distances along the path in case of stochastic, regularizedwith amplitude and phase masks filaments and observed a stable filament array formation incase of amplitude masks.
