Laser Beam Propagation through Oceanic Turbulence 13 strength and beam radius (i.e., ε ¼ 10 5 m 2 = s 3, χ T ¼ 10 7 K 2 = s, w ¼ 3 and W 0 ¼ 0: 05m) shown in Figure 3, the value of r 2. modify the propagation of laser beams through atmosphere []. In weak atmospheric turbulence, the modifications can be described as three separate effects: wander, spreading, and scintillation each of which can be detrimental to applications requiring long range propagation of the beam [4,7]. For instance, beam wander, or deflections inCited by: The principal characteristics of the propagation of a laser pulse along a horizontal atmospheric path made turbid by soot are determined. It is shown that, depending on the ratio of the path length to the characteristic length of thermally induced self-focusing and self-defocusing effects in free atmosphere, the effects of either Bouguer attenuation or thermal distortions may be primarily. @article{osti_, title = {Multiple-scattering analysis of laser-beam propagation in the atmosphere and through obscurants}, author = {Zardecki, A and Gerstl, S A.W.}, abstractNote = {The general purpose, discrete-ordinates transport code TWOTRAN is applied to describe the propagation and multiple scattering of a laser beam in a nonhomogeneous aerosol medium.

The book introduces optical wave propagation in the irregular turbulent atmosphere and the relations to laser beam and LIDAR applications for both optical communication and imaging. It examines atmosphere fundamentals, structure, and content. It e. In this paper, the effect of thermal blooming of an Airy beam propagating through the atmosphere is examined, and the effect of atmospheric turbulence is not considered. The changes of the intensity distribution, the centroid position and the mean-squared beam width of an Airy beam propagating through the atmosphere are studied by using the four-dimensional (4D) computer code of the time.

Another set of laser applications associated with the propagation of coherent radiation in the atmosphere requires the solution of both direct and inverse problems related to this complex subject. The kind of applica­ tion in question is the use of lasers for long-range monitoring of various physical parameters of the atmosphere-a new and. The beam propagation method (BPM) is an approximation technique for simulating the propagation of light in slowly varying optical is essentially the same as the so-called parabolic equation (PE) method in underwater BPM and the PE were first introduced in the s. When a wave propagates along a waveguide for a large distance (larger compared with the wavelength. A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic term "laser" originated as an acronym for "light amplification by stimulated emission of radiation". The first laser was built in by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur.

In this paper, the influence of atmospheric turbulence and thermal blooming on focus characteristics of laser beam is given for several typical lasers with different wavelength. The excursion of the laser beam axis for long distance propagation in atmosphere is also obtained for several laser beam.

As we know, it is impossible to avoid the beam wander effect for laser propagation. Therefore, achieving small beam wander is imperative. In this paper, the relative beam wander describes the increment of beam wander between focused and collimated beam, and this quantity benefits us to obtain small value of beam by:.

The optical effects of atmospheric turbulence on the propagation of low power laser beams are reviewed in this paper. The optical effects are produced by the temperature fluctuations which result in fluctuations of the refractive index of air.

The commonly-used models of index-of-refraction fluctuations are presented. Laser beams experience fluctuations of beam size, beam position, and Cited by: 2.propagation situations, and the expressions for the deflection and radius will allow for the evaluation of their corrected values.
