Simple Estimate of the Impact of M<sup>2</sup> and Strehl Ratio on the Effective Focusable Spot Size
A simple method (first-order approximation) to determine the impact of M<sup>2</sup> and the Strehl Ratio on the effective focusable spot size avoiding complex propagations of the beam wavefront is proposed. The model is based upon previous models and the definition of M<sup>2</...
