摘要：

We have achieved effective third-harmonic generation (THG) by cascading second-harmonic and sum-frequency generation in a single cerium-doped KTiOPO4 crystal by using femtosecond laser pulses at 1.32 mu m. A conversion efficiency of 0.17% was achieved with an average pump power of 35 mW. Furthermore, a unique quadratic power dependence for this type of THG was confirmed. We developed a theory and obtained an analytical solution for the THG. The solution exactly describes the measured characteristics of the THG. (C) 2000 Optical Society of America.
