摘要
对平顶方波在 CLBO晶体上的 类及 类相位匹配条件下的倍频光束转换效率 ,进行了理论模拟计算 ,给出了影响谐波转换效率的各种因素 ;并将其与高斯光束的谐波转换效率进行了比较 ,得出在相同条件下 。
Studied the theoretical properties of flattened Gaussian beams second harmonic generation and makea a numerical simulation on the crystal CLBO phase matching in type I and type Ⅱ.The effected factors of the conversion efficiency were given out.Compared the SHG conversion efficiency on the flattened Gaussian beam with the Gaussian beam under the same condition and found out the former is higher than that of the latter.
