Abstract: We discuss theoretically and demonstrate experimentally the
robustness of the adiabatic sum frequency conversion method. This tech-
nique, borrowed from an analogous scheme of robust population transfer in
atomic physics and nuclear magnetic resonance, enables the achievement
of nearly full frequency conversion in a sum frequency generation process
for a bandwidth up to two orders of magnitude wider than in conventional
conversion schemes. We show that this scheme is robust to variations in the
parameters of both the nonlinear crystal and of the incoming light. These
include the crystal temperature, the frequency of the incoming field, the
pump intensity, the crystal length and the angle of incidence. Also, we
show that this extremely broad bandwidth can be tuned to higher or lower
central wavelengths by changing either the pump frequency or the crystal
temperature. The detailed study of the properties of this converter is done
