摘要：
We have efficiently generated ultrafast coherent ultraviolet (UV) pulses based on second-harmonic generation in a periodically-poled KTiOPO4 crystal with the period as short as 2.55 mu m. The highest output power is measured to be 20.1 mW at 377.1 nm with the conversion efficiency of 15.6%. Such an output wavelength is probably among the shortest ones generated by forward second-harmonic generation in a periodically-poled KTiOPO4 crystal.
