Beschreibung:

We report on efficient broadband sum-frequency generation, converting a 140 THz near-infrared bandwidth to the visible regime with photon conversion efficiency greater than 90%. Using a 20-mm-long aperiodically adiabatively poledKTPcrystal, the spectral range 660-990nmwas converted to 405-500nmusing a strongpumpwave at 1030nm. The photon conversion efficiency was confirmed to be 92 ± 0.5% when pumped with an intensity of 0.94 GW?cm 2 . Our experimental results agreed very well with analytic predictions and numerical simulations. © 2014 Optical Society of America.
