Photon-Count Distributions and Irradiance Fluctuations of a Log-Normally Distributed Light Field*

Experimental and theoretical investigation of loss of coherence on scattering of a beam with helical wavefront

“…The scattering of laser light through an RGG has drawn a great interest for producing a pseudo thermal light or light with partial coherence and found variety of applications [25][26][27][28][29][30]. This method for producing partially coherent light is very convenient because here the coherence could be controlled easily just by changing the rotation speed of the RGG.…”

Characterization of Photon Statistical Properties with Normalized Mandel Parameter

“…[1] Many techniques were developed, including counting statistics with fixed time interval, [2−4] coincidence-counting experiments, [2] arrival-time-interval analysing, [5] twotime correlations, [1,6,7] and so on. They were intensively used to reveal intensity fluctuations of classical photon emissions (lasers, [3] thermal light, [1,5] pseudo-thermal light, [4,6] etc. ), nonclassical photon emissions (resonant fluorescence, [8−11] single photon sources, [12−14] etc.…”

“…A He-Ne laser (633 nm) beam was focused on a rotating ground glass (RGG) by a lens (f = 75 mm) to produce PTL, as described in Refs. [4,6]. Then the centre of the fanningout beam passed through two apertures (A1 and A2, in diameter of about 0.2 mm) at about 0.1 m and 2.0 m away from the RGG, which ensures the transmitted PTL beam was in one coherent area.…”
