Abstract

We experimentally investigate filamentation and supercontinuum generation in a birefringent medium (BBO crystal), in the self-focusing regime where intrinsic cubic nonlinearity is either enhanced or reduced by the second-order cascading due to phase-mismatched second harmonic generation. We demonstrate that the supercontinuum spectral extent is efficiently controlled by varying the phase mismatch parameter. In the range of negative phase mismatch, we achieve full control of the blue-shifted spectral broadening, which is very robust and independent on the input pulse energy. In the range of positive phase mismatch, both the blue-shifted and the red-shifted spectral broadenings are controlled simultaneously, however showing a certain dependence on the input pulse energy. The results are interpreted in terms of complex interplay between the self-phase-matched second harmonic generation, which is a process inherent to narrow ultrashort pulsed laser beams and concurrent self-steepening processes which arise from cubic and cascaded-quadratic nonlinearities.

Figures (6)

Fig. 1
Fig. 1 (a) Calculated phase mismatch parameter Δk. (b) Nonlinear refractive indices: n 2 kerr (blue dash-dotted line), n 2 casc (red dotted curve) and n 2 eff (green solid curve) versus the angle θ. Note the two available propagation regimes: self-defocusing, where n 2 eff < 0 and self-focusing, where n 2 eff > 0. The shaded areas mark the angle range where control of SC spectral extent was experimentally observed.
Fig. 2
Fig. 2 Experimentally measured spectra as functions of angle θ with various input pulse energies: (a) 160 nJ, (b) 190 nJ, (c) 280 nJ, (d) 410 nJ. Each plot is composed of 110 individual spectra. The logarithmic intensity scale is used to highlight fine spectral features. The solid and dashed curves depict the self-phase matching curve for an axial SH component and the corresponding wavelengths in the spectrally broadened fundamental pulse, respectively.
Fig. 3
Fig. 3 The total second harmonic energy conversion efficiency as a function of the angle θ with the input pulse energies of 160 nJ (red solid curve) and 280 nJ (blue solid curve). The inset shows a magnified fraction of the graph, which distinguishes between the self-phase-matched and phase mismatched (green dashed curve) SH generation.
Fig. 4
Fig. 4 The blue-shifted cut-off of the SC spectrum as a function of the input pulse energy and angle θ.
Fig. 5
Fig. 5 The axial cross-correlation functions measured with two input pulse energies: 190 nJ (top row) and 280 nJ (bottom row) and at various angles θ: (a),(d) 32.4°, (b),(e) 37.5°, (c),(f) 42.6°.
Fig. 6
Fig. 6 Experimentally measured spectra in the range of positive phase mismatch with the input pulse energies of (a) 0.6 μJ and (b) 1 μJ. The curve designations are the same as in Fig. 2. A weak signal centered at 400 nm is the phase-mismatched SH.
