摘要：

Mid-infrared radiation near 2.8 mu m was generated by difference-frequency generation in an 80-mm-long periodically poled Ti:LiNbO3 channel waveguide by pump radiation near 1.55 mu m (tunable external-cavity laser) and a signal radiation of 3.391 mu m (He-NE laser). We obtained a normalized conversion efficiency of 105% W-1, which is to our knowledge the highest value ever reported.
