| 摘 要： | 为了探究PPLN外部谐振倍频腔的输出模式,从菲涅尔-基尔霍夫衍射积分公式出发,采用快速傅里叶变换法(FFT)和Fox-Li迭代法数值模拟高斯反射率圆形平凹倍频腔输出基模的场强分布、相位分布和光束质量M2因子,同时与圆形双凹倍频腔做了比较.计算结果表明,两类倍频谐振腔输出塞模均为高斯分布,腔长变化对两类倍频腔输出光束质量...

| Abstract: | To study the output mode distribution of the frequency doubling resonant in PPLN, the field distributions and beam quality M2 factor of the plano-concave resonator or dual-cavity were calculated and compared. The output fundamental modes of them with tilted Gaussian-reflectivity mirrors were simulated with Fourier transformation method and Fox-Li iterative method. The results show that the output fundamental mode of the frequency doubling external resonants is Gaussian distribution, and cavity length change... |
