Fig. 2. High-order degree of coherences of pseudothermal and coherent light fields (dashed line is theoretical value of pseudothermal light field and solid line is theoretical value of coherent light field). (a) g(2) (0) as function of exposure time with counting rate of 5.12×108 s-1; (b) g(3)(0) as function of exposure time with counting rate of 5.12×108 s-1; (c) g(3) (0) as function of counting rate with exposure time of 300 ns; (d) g(n) (0) as function of order number with counting rate of 5.12×108 s
