Rayleigh range meaning
WebThe Rayleigh range where zR is the “Rayleigh range” -a key parameter in describing the propagation of beams near focal points. If w0 is the beam waist at a focal point, then we can write qat that value of zas: 2 0 R w z q j zfocus R It is, roughly, the focal spot area divided by . Now, how does qchange as zincreases? WebSIGNIFICANCE OF THE REDUCTION OF RCS If each of the range or power equations that have an RCS ( F) term is evaluated for the significance of decreasing RCS , Figure 6 results. Therefore, an RCS reduction can increase aircraft survivability. The equations used in Figure 6 are as follows:

A very small amount of the scattered light (~ 1 in 107) is shifted in energy from the laser frequency. This shift is known as a Raman or Stokes shift. At room temperature, the anti-Stokes-shifted Raman energy is
WebIn this sunrise image, the blue sky, yellow Cirrus clouds and orange Altocumulus clouds result from both Rayleigh and Mie scattering. Rayleigh scattered produces blue sky and the color the clouds receives. Mei scattering is responsible for the color we see.

This distance is given by the Rayleigh range of the output beam: $$ z_{\rm Rayleigh} = \frac{\pi w_f^2}{\lambda} . $$ So we see that, in order to increase this distance, we would also have to increase the size of the beam.
