Teaching Notes WebAug 24, 2024 · This is typical of a tube that has shifted to a higher-order transverse mode. TEM01 is the most common mode to shift to; it’s sometimes called the “donut mode” and in theory is donut-shaped but in practice seems commonly to look like the two dots you see here. [Edit: TEM₀₁* (donut) is different from TEM₀₁, which looks like two dots.] howe bridge mill athertonWebSo different colors of light will have a slightly different Brewster angle); the only way in which laser light is different from "ordinary" light in this case is the fact that laser light is typically linearly polarized, so that the reflection coefficient for a particular angle can be changed simply by rotating the laser pointer. howe brothers photographs

"WebA beamsplitter is an optical component used to split a beam of incident light into two parts in a laser or illumination system.
