Shlomo Ruschin, Elad Yaakobi, Eyal Shekel

摘要:

我们建议高斯含量作为一个可选的质量参数的激光束的表征。它被定义为给定场与最佳定义的高斯的重叠积分。该定义特别适用于以相干特性为目标的应用。数学定义和基本的计算程序,以及结果的基本光束轮廓。作为应用实例,阐述了激光阵列的相干合成和二极管激光器与单模光纤(SMF)之间的最佳耦合。实验证实了高斯含量的测量及其在传播时的守恒性。

英文摘要:

We propose the Gaussian Content as an optional quality parameter for the characterization of laser beams. It is defined as the overlap integral of a given field with an optimally defined Gaussian. The definition is specially suited for applications where coherence properties are targeted. Mathematical definitions and basic calculation procedures are given along with results for basic beam profiles. The coherent combination of an array of laser beams and the optimal coupling between a diode laser and a single-mode fiber (SMF) are elaborated as application examples. The measurement of the Gaussian Content and its conservation upon propagation are experimentally confirmed.
