Abstract

We present simultaneous efficient second- (SHG) and third-harmonic generation (THG) in a single periodically-poled KTP waveguided crystal pumped by a compact femtosecond Yb-based laser in a condition of exactly phase-matched frequency doubling and nonphase-matched sum-frequency mixing processes. Internal conversion efficiency as high as 33% for SHG (532nm) and ∼2% for the cascaded THG (355nm) is reported. We believe this to be a clear experimental demonstration that strong third-harmonic can be generated in frequency doubling crystals through a nonphase-matched sum-frequency mixing process.
