摘要

利用聚焦轴对称偏振光束，利用椭圆率的空间变化证明了二次谐波产生的横向模式转换。厄米-高斯或拉盖尔-高斯光束的高阶横模叠加形成特殊的强度模式。

Second harmonic generation using axially symmetric, polarized beams with spatial variation of ellipticity

Transverse mode conversion by second harmonic generation is demonstrated using focused axially symmetric, polarized beams with spatial variation of ellipticity. Superposition of higher order transverse modes of Hermite-Gaussian or Laguerre-Gaussian beams forms peculiar intensity patterns.
