Analytical Expressions

New analytical representations for the truncated spectral characteristics of the four-point coherence function of a laser beam propagating in a turbulent medium are obtained. These representations are valid for any level of fluctuations of the refractive index in air. For two particular cases they turn into exact analytical representations previously derived by the authors with using of an integro-functional equation for truncated spectral characteristic of the four-point coherence function. A constructive procedure for obtaining approximate analytical expressions of the four-point coherence function of a laser beam propagating in a turbulent medium is proposed.

It is pointed out that the frequency spectrum of a laser beam is not broadened when the beam is focused by a normal lens. This assertion contradicts the conclusion reached by the authors of the articles cited in the title above.
