title: Tunable upconverted optical parametric oscillator with intracavity adiabatic sum-frequency generation.
abstract: We experimentally demonstrate efficient tunable upconversion by cascading optical oscillation and wideband adiabatic sum-frequency generation in a single KTiOPO(4) 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.
