Rayleigh length rp
WebNote that the Rayleigh length scales with the square of the beam waist radius, so that large beam radii are essential for long propagation distances. For beams with non-ideal beam … WebNov 18, 2015 · z R (Rayleigh) is typically relatively small, unless it’s a highly collimated beam. That means that s” will dominate the denominator of the second term. Unless, s-f is very small. In other words, here is when you need the Gaussian formula: A highly collimated beam; Any beam that has a distance to lens (s) very similar to the lens focal length.

Webthe simulated gain G=G0 versus Rayleigh length (normal-ized by the undulator length: z0 ¼ Z0=L) as the FEL peak gain is increased. Clearly the simple theory holds only when the peak gain is less than a few percent. For a cold cavity (no gain), a characteristic feature of short Rayleigh length resonators is their extreme sensitiv-
