[已解决]请教zemax物理光学传输问题

hwsywu

zemax准直器仿真，请问在物理光学传输中图解中显示的3个光斑尺寸的含义以及区别（1.size，2.waist，3.beam width，为什么有这么小的尺寸差异）？在下不是光学科班出身，恳请大家帮忙解答，谢谢!

Consider a Gaussian beam with waist ω0，The pilot beam is an ideal Gaussian beam, with a waist, beam size, phase radius, and relative z position. beam waist
Applicable to all beams, Gaussian or not, coherent and incoherent.The beam width (defined here as the beam radius at the 1/e2 intensity point)

pilot beam为理想高斯光束，看了一下，差异在于beam waist是高斯光束的束腰，而beam width为非相干光和高斯光的在1/e2处的光斑半径
