Continuous manipulation of tunable mixed classical light from coherent light to pseudothermal light

We demonstrated tunable mixed classical light (TMCL) using a mixture of a laser and a pseudothermal light. The TMCL was generated by adjusting the photon number ratio of a laser and a pseudothermal light. The photon number statistics of the TMCL continuously changed from the Poisson distribution to the Bose-Einstein distribution. The g((2)) (0) value of the TMCL was measured using the Hanbury Brown-Twiss method, and we could arbitrarily control the g((2)) (0) value between 1.0 and 1.7. The experimental g((2)) (0) value of the TMCL as a function of the photon number ratio of the two light sources was in close agreement with the calculated result.
