Effect of Coherence Coefficient of Single Mode Coherent State Light Field on Photon Number Distribution
Because the coherence coefficient has great influence on the maximum probability interval of photon number distribution,this paper studies the effect of three different interval coherence coefficients on the photon number distribution in the single mode coherent state light field in detail,and analyzes the maximum probability distribution and half-height width of different distribution intervals.For example,when the coherence coefficient varies from 0.01 to 0.1,the number of photons is mainly distributed within 3.When the coherence coefficient varies in the range of 1～10,the photon number is mainly distributed within 25.When the coherence coefficient varies in the range of 10～100,the number of photons is mainly distributed within 150.Finally,the photon number distributions with coherence coefficients of 0.1,1,10 and 100 in the three intervals are compared and analyzed.The study of photon number distribution characteristics in different intervals can be used to regulate light field states and provide theoretical basis for practical application.
