At the same time we obtained that the shg conversion efficiency of the flattened gaussian beam is higher than that of the gaussian beam under the same condition ; in section 3 , we have computed the theoretical conversion efficiency of the thg on the flattened gaussian beam , where we also have worked out the type - i and type - 11 ( 1 ) thg conversion efficiency curves versus the same effectors , and found the flattened gaussian beams thg conversion efficiency is higher than that of the gaussian beam too ; in the section 4 , we have simulated the field distribution of the shg and thg wave on the flattened gaussian beam 在相同條件下,得出了平頂高斯光束的倍頻轉換效率高于高斯光束的倍頻轉換效率;第三章對平頂高斯光束在clbo晶體上的類和類混頻轉換效率與其影響因素的關系進行了數值模擬和計算,并同高斯光束進行比較,同樣得到混頻時,平頂高斯光束的轉換效率高于高斯光束的混頻轉換效率的結論;第四章模擬計算了平頂高斯光束的倍頻、混頻波橫向光場的分布形式,得到了諧波場仍為均勻平頂高斯光束的結果。

We also calculated the threshold and efficiency curves with the crystal length , pump power , wavelength of signal wave and mismatch etc on the single resonance oscillator ( sro ) of clbo . the most obviously difference of dro and sro is that when the pump power is higher and the crystal length is longer , the efficiency curves become smooth but not descend in comparing sro to that of dro 在對單諧振和雙諧振的振蕩閾值和轉換效率的理論研究中,得到了單諧振與雙諧振不同的是:在單諧振情況下,隨泵浦強度、晶體長度的增加,轉換效率曲線只有飽和的趨勢,而無下降趨勢的結論。

The results showed that the torque ratio and efficiency curve are almost not affected by width ratio , whereas the torque capacity performance changes especially when the speed ratio is less than 0 . 6 結果表明,隨寬度比減小變矩比和效率基本不受影響,而透穿性則由正透穿逐漸變為混合透穿,在速比大于0 . 6時傳動性能基本沒有差異。

In the section 3 , we calculated the threshold and efficiency of double resonance oscillator ( dro ) in plane wave of clbo ; we also got the efficiency curves of clbo in gaussian beam 第三章分析和數值模擬計算了平面波雙諧振情況下clbo晶體的振蕩閾值和轉換效率曲線,同時給出了高斯光束的轉換效率曲線并與bbo晶體進行了比較。

Besides , efficiency curves versus clocking positions can be improved globally by changing rotor ' s position from the middle of two stator rows or by reducing the distance between two stators in axial direction 另外,處于兩靜葉排正中的動葉位置的前后移動或縮短靜葉排間的距離均能帶來時序效應影響下效率的整體提升。
