WebMar 17, 2024 · The intensity clamping can also occur even in the tightly focused filaments, while its peak intensity can surpass the clamping intensity at least one order of magnitude (Kiran et al 2010). Moreover, clamping intensity increases with the numerical aperture of the external focusing system. WebThe results indicate that clamping intensity inside the filament is sensitive to laser polarization, which has to be considered to fully understand polarization-related phenomena. Laser polarization and its intensity inside a filament core play an important role in …
WebNov 1, 2024 · Because two low-intensity annular beams coherently supply the energy to the filament core and the clamping intensity of 400 nm filament is lower than the 800 nm one, the input energy (1. 2 mJ) of them maintains sufficiently a long-distance propagation of the two-color filament, which is extended to 10 m that increases about one order of ... WebFeb 1, 2002 · We may ask, how a clamping of the intensity inside the filament to a maximum value is possible if the input energy is further increased, in the present …
