Diffraction loss

$Diffraction loss$

$Diffraction loss$ .

The magnitude of the diffraction loss depends on the geometric dimensions of the resonator, the type of field distribution.

$Diffraction loss$

The mode distribution coincides with the field distribution in the waveguide:

$Diffraction loss$ ,

if the field is round, it is described by the Bessel formulas, $Diffraction loss$ - wave numbers, n, m - the number of field variations along x or y.

$Diffraction loss$ - the number of Frinel.

Obviously, with increasing cavity length, diffraction losses increase. With an increase in a (mirror size), diffraction losses will decrease.
