WebJan 10, 2024 · Regarding your first question, the Beam waist POP asks for is the 1/e2 radius if the beam profile is Gaussian. Fiber Mode Field Diameter (MFD) is typically defined as the diameter where the intensity drops to 1/e2 of the peak intensity. Since POP beam size is the half width or the 1/e2 radius, you can use MFD/2 as the beam waist size.
