Abstract

We present measurements of the supercontinuum emission (SCE) from ultrashort Ti:Saph laser pulse filamentation in air in a tightly focused geometry. The spectral broadening of SCE indicates that peak intensities exceed the clamping value of a few 1013 W/cm2 obtained for filamentation in a loose focusing geometry by at least one order of magnitude. We provide an interpretation for this regime of filamenation without intensity clamping.

Fig. 1

Typical supercontinuum emission spectrum from the propagation of a linearly polarized (LP) and a circularly polarized (CP) 45 fs laser pulses in air at an input power of ∼ 100 GW focused by using f/6 focusing geometry. The inset shows the ratio between the spectral intensities of the CP and LP pulses.

Typical beam characteristics for filamentation in a loosely focusing regime (f = 200 cm). (a) beam curvature C = w −1 dw / dz; (b) power (c) peak intensity and (d) beam width and phase fronts vs propagation distance z. Input parameters: P(z = 0) = 4P cr, w(z = 0) = 2.25 mm, f = 2 m.

Same as in Fig. 3 but for a tight focusing geometry. The parameters of the input beam at z = 0 are w 0 = 200 μm, f = 0.21 cm (same numerical aperture as in the experiment). P = P cr and I 0 = 5 × 1012 W/cm2.
