We show the principle of operation of a setup to adiabatically shape solitons in quadratic nonlinear media to different beam profiles and widths or different fractions of energy carried by the second-harmonic wave. The shaping mechanism is based on soliton generation and propagation in chirped, quasi-phase-matched samples.
