摘要
Radiation in the wavelength range from 6.0 to 6.2 mu m, which is in a highly absorptive region of LiNbO3, was generated. A 5 mol % MgO-doped, periodically poled LiNbO3 was used as an optical parametric oscillator. The oscillator was pumped by a Nd:YAG laser with an I I ns pulse duration. The signal and idler waves generated were focused on another periodically poled LiNbO3 for difference frequency generation. The maximum pulse energy obtained was 0.21 mu J at 6.05 mu m.
