“…Beam breakup starts evolving along the major axis and ends up with stable and entirely predictable MF patterns. To this regard, reproducible MF patterns by slightly elliptical beams had been observed in various nonlinear media: water [9], air [10], BK7 glass [11], fused silica [12], and carbon disulfide [13], all revealing the universality of the deterministic breakup process.…”

Self-focusing and multiple filamentation of highly elliptic laser beams is studied experimentally in condensed media with Kerr nonlinearity (water and fused silica). We show that highly elliptic laser beam initially breaks up into one-dimensional array of filaments, producing deterministic and periodic patterns. At higher pump energies, the interplay between the neighbouring filaments gives rise to formation of complex two-dimensional spatial structures.

The spatial evolution of plasma filaments in air induced by femtosecond laser pulses is investigated experimentally. Several major filaments and small scaled additional filaments are detected in the plasma channel. The complicated interaction process of filaments as splitting, fusion and spreading is observed. The major filaments propagate stably, and the small scaled additional filaments can be attracted to the major filaments and merged with them. The major filaments are formed due to the perturbation of initial beam profile and the small scaled filaments are mainly caused by the transverse modulational instability.
