Experimental generation of nonuniformly correlated partially coherent light beams

Abstract

We report the experimental realization of nonuniformly correlated partially coherent light (NUCPCL) beams by passing laser beams through a phase-only spatial light modulator. The characteristics of NUCPCL beams whose coherence is of Gaussian distribution as well as inverse Gaussian distribution are studied theoretically and experimentally. It is shown that the experimental observations are in agreement with our theoretical analysis. NUCPCL beams may have some applications in optical manipulation.

Temporal self-splitting of optical pulses

“…However, they are not the only extraordinary phenomena caused by partial coherence; some correlation functions can decrease scintillation in atmospheric turbulence [17], while others increase the resolving power of imaging systems [18,19]. Many of these sources have been experimentally generated, and their properties are now rather well known [20][21][22][23][24][25][26][27]. A detailed review on generation and propagation of various partially coherent beams can be found in [28] and the references therein.…”

“…However, the only model beam that not being of uniform correlation (e.g., Schell-model correlation) is the spatially varying correlated sources, proposed in [10,11]. In recent years, more and more attention has been paid to these beams with special correlation distribution [12][13][14][15][16][17], due to their interesting features, such as locally sharpened and laterally shifted intensity maxima [4]. The behavior of scalar beams of nonuniform correlation, in isotropic random media, was explored in [12], which introduced a class of electromagnetic beams with nonuniform correlation distribution [5].…”

“…The scintillation properties of NUC beams, in atmospheric turbulence, were investigated in [14]. The experimental realization of a NUC partially coherent beam was reported in [15]. In addition, plane-wave pulses with nonuniform correlation distributions, and their propagation in dispersive media, have also been investigated [16,17].…”

Effect of the atmospheric turbulence on a special correlated radially polarized beam on propagation

“…Since Gori and co-workers derived the sufficient condition for devising genuine correlation functions for partially coherent scalar and vector beams [3,4], various partially coherent beams with different kinds of correlation functions have been introduced theoretically [5][6][7][8]. Meanwhile, several methods were proposed to produce such kinds of partially coherent beams [9][10][11][12]. Of particular interest is that such partially coherent beams exhibit some extraordinary propagation characteristics even in free space.…”
