拉盖尔-高斯光束光限幅

Optical limiting using Laguerre-Gaussian beams

Weiya Zhang, Mark G. Kuzyk

摘要:

我们证明了光限幅使用自透镜效应的高阶拉盖尔-高斯光束在薄的染料掺杂聚合物样品,我们发现是一致的,我们的模型使用高斯分解。限制所需的样品中的峰值相移小于基本高斯光束,具有增加的灵活性,即非线性介质可以放置在光束焦点的前面或后面。

英文摘要:

We demonstrate optical limiting using the self-lensing effect of a higher-order Laguerre-Gaussian beam in a thin dye-doped polymer sample, which we find is consistent with our model using Gaussian decomposition. The peak phase shift in the sample required for limiting is smaller than for a fundamental Gaussian beam with the added flexibility that the nonlinear medium can be placed either in front of or behind the beam focus.
