Abstract:An external cavity is developed for terahertz-wave parametric oscillators pumped by all solid state picosecond lasers (ps-TPOs). To achieving the ps-TPOs high-powered operation, the doped concentration of the MgO: LN crystal, the focusing spot size in MgO: LN crystal, the length of the MgO: LN crystal and the optical-to-THz conversion efficiency are optimally designed and calculated. The calculated results can provide a comprehensive theoretical basis for the ps-TPOs using difference- frequency method to produce tunable terahertz-wave radiations in MgO: LN crystal.
Keywords:terahertz-wave parametric oscillators  difference-frequency  picosecond  MgO: LiNbO3 crystal
