Figure Legend:
The intensity profile (a) and phase distribution (b) of the single ring LG beam modulated by a radially logarithmic phase factor and a
spiral phase factor. The parameters used in simulation of intensity distribution (a) and phase distribution (b) are as follows: m = 2, n
= 30, p = 50, w = 1500. (c) the phase distribution of the radially logarithmic phase modulation with vortex of unit charge, i.e., $\exp
[i(\vartheta _0 + p\log (r_0 /w))]$exp[i(ϑ0+plog(r0/w))]. The parameters used in Fig. 1(c) are as follows: m = 1, n = 0, p = 50, w =
1500.

(a) The interference patterns of computer-generated hologram of single ring LG modulated by a radially logarithmic phase factor and
a spiral phase factor with a plane wave; (b) theoretical computer simulation of the intensity profiles of generated confluent
hypergeometric beams. The computer simulation is actually the result of the two-dimensional fast discrete Fourier transform
corresponding to far-field Fraunhofer diffraction of optical field expressed as Eq. . The parameters used in simulation of interference
pattern and the intensity profiles of generated confluent hypergeometric beam are as follows: m = 2, n = 30, p = 50, w = 1500, α =
0.05.

Figure Legend:
Experimental setup for generating confluent hypergeometric beams. The laser wavelength is 633nm. The spatial light modulator
(SLM) is a twisted nematic liquid crystal display with 1024 × 768 pixels (each pixel has 14 μm × 14 μm size). The computergenerated hologram displayed on the SLM through VGA cable is simulated with computer using following parameters as m = 2, n =
30, p = 50, w = 1500, α = 0.05.
