采用具有大动态范围的Ⅰ/Ⅱ角度失谐和Ⅱ/Ⅱ偏振失配双倍频双混频技术方案,对整形脉冲的三倍频效率进行了数值模拟计算分析,并与单倍频单混频方案的结果进行了比较。数值计算结果表明,双倍频双混频方案比单倍频单频方案更利于整形脉冲的三倍频。
The triple-frequency efficiency of the shaping pulse is numerically simulated and calculated by using the double-frequency double-frequency mixing technique with Ⅰ / Ⅱ angle mismatch and Ⅱ / Ⅱ polarization mismatch with large dynamic range. The results of the frequency plan were compared. The numerical results show that the double-frequency double-mixing scheme is more advantageous than the single-frequency single-frequency scheme in terms of the third harmonic of the shaping pulse.
