Light field combination operator excited chaotic field is constructed by operation of light field combination operator on chaotic field. Its squeezing, antibunching effect, statistical property and negativity of Wigner function are analysed by calculating two orthogonal components of the light field fluctuations, secondorder correlation function, Mandel Q parameters and Wigner function, respectively. The influences of superposition coefficient of operators and the average photon number of the field on quantum properties are discussed. Results show that the nonclassical property of the field is weakened with the increase of average photon number of the field. On the other hand, its antibunching effect and sub- poissonian statistical property are strengthened as the ratio of photon addition operator in superposition operation increases. The result shows that the increase of the ratio of photon addition operator in superposition operation can help strengthen antibunching effect and sub-poissonian distribution property.
