How to get the right laser spot at the right distance? – Part 2
In part one of this blog series, we set out to answer the question of “how to get the right laser spot at the right distance?” As we went on to explain, this simple question doesn’t have a simple answer, especially when we are talking about single-mode fiber optics. In that post, we took the time to go through
an introduction of Gaussian beam optics and provided a few examples of how that can be used to determine the lens you need to choose for a given spot size. In part two, we are going to explore the far more straightforward case of imaging a multi-mode las… Read More
