This part of ISO 11146 specifies methods for measuring beam widths (diameter), divergence angles and beam propagation ratios of laser beams in support of ISO 11146-1. It provides the theoretical description of laser beam characterization based on the second-order moments of the Wigner distribution, including geometrical and intrinsic beam characterization, and offers important details for proper background subtraction methods recommendable for matrix detectors such as CCD cameras. It also presents alternative methods for the characterization of stigmatic or simple astigmatic beams that are applicable where matrix detectors are unavailable or deliver unsatisfying results.

ISO/TR 11146-3:2004 激光和激光相关设备.激光束宽度、发散角度和束扩散率.第3部分:内在和几何激光束分类、扩散和试验方法细节 由 ISO 11146:1999 变更而来。
在推荐电压范围的低端运行激光模块也将有助于延长激光的寿命。 激光发散角指定光束在一定距离内的散布量。我们所有的光束发散规格均为全角度值。电磁束的束发散度是束直径或半径随距发出电磁束的光学孔径或天线孔径的距离而增加的角度度量。该术语仅在“远场”中有用,远离光束的任何焦点。然而,实际上,取决于孔径直径和工作波长,远场可以在物理上接近辐射孔径开始。 ...
