Reconstruction of a multipixel image: a, image at the input face of the crystal; b, image at the output face of the crystal under conditions of the linear propagation regime; c, reconstructed image at the output face for the pump wavelength in the strongly nonlinear regime; d, reconstructed image at the output face for the signal wavelength in the strongly nonlinear regime.

Fig. 2

Image of the crystal output face at selected Z positions. a, pump beam in the linear propagation regime (low intensity). At Z=0 each pixel has 30 μm FWHM, and the step between pixels is 108 μm. b, signal and pump beams in the strongly nonlinear regime.

Fig. 3

Output beam diameter with respect to pump-waist position: comparison between the linear and the solitary propagation regimes. Trapping between the signal and pump beams is evident for values of Z ranging from -5 to +27 mm. The vertical lines represent the pump-waist position at the input and output of the crystal face. Pump-beam parameters: waist peak intensity, 120 GW/cm2; minimum waist diameter, 40 μm FWHM. LBO, lithium borate.

Fig. 4
Fig. 4

Threshold for soliton excitation with respect to pump-waist position. The threshold is defined as the lowest pump power at which, at the output crystal face, a narrow beam (in the green band) is detected whose diameter does not change significantly with increasing pump power. The vertical lines are the same as in Fig.  3. Minimum waist diameter, 40 μm FWHM. LBO, lithium borate.
