【Abstract】 The overall characteristics of hi gh efficiency third harmonic conversion for type Ⅰ/type Ⅱ angle-detuning and type Ⅱ/type Ⅱ polarization mismatch schemes (two doubler and two tripler) have been analyzed by numeric simulation with high power large dynamic input fundame ntal waves. The effects of partial polarization beam on both schemes have also b een simulated. The results show that the type Ⅰ/type Ⅱ angel-detuning scheme is better than type Ⅱ/type Ⅱ polarization mismatch scheme under above conditio ns.更多还原
