描述了一类新的非线性光学过程，其中n次谐波的辐射是通过使用（2n+1）阶非线性产生的。利用奇阶非线性，该过程允许在各向同性材料中产生和放大奇阶和偶阶谐波。此外，在不使用双折射的情况下，该过程始终可以在正常色散材料中进行相位匹配。给出了蓝宝石样品产生锥形三次谐波发射的实验结果。
A novel class of nonlinear optical processes is described in which radiation at the nth harmonic is generated through the use of a (2n+1)-order nonlinearity. Utilizing an odd-order nonlinearity, this process allows for the generation and amplification of both odd- and even-order harmonics in isotropic materials. Additionally, this process can always be phase matched in normal-dispersion materials without the use of birefringence. Experimental results are presented in which conical third-harmonic emission is generated from a sapphire sample.
