摘要：
A wideband piezoelectric transducer was used to receive signals from different filaments inside a multiple filament. A technique for calculating parameters of filaments in each laser pulse has been proposed. For a regularized superfilament created using of the amplitude mask a growth of absorbed linear energy density has been observed by more than an order compared to a single filament.
