Abstract :
Summary form only given. The combination of sum frequency generation (SFG) and SHG processes has generated 590 mW of green light from a planar periodically poled lithium niobate (PPLN) waveguide, which, to the best of our knowledge, is the highest power ever reported from such a device. In this experiment, combining the SFG and SHG processes within the planar waveguide produced 35% more green power than would be obtained by frequency doubling the two infrared polarizations separately.
