We experimentally demonstrate efficient tunable upconversion by cascading optical oscillation and wide-
band adiabatic sum-frequency generation in a single KTiOPO4 crystal, yielding red light tunable over a 6.2
nm wavelength band. The conversion efficiency of the 1064 nm pump to the red output was up to 4.7%, and
with the highest pump power of 1.5 W we obtained 71 mW of average power at 637 nm. 2010 Optical
