摘要
构造了激发奇q相干态a+mq α〉oq 和激发偶q相干态a+mq α〉eq,并通过数值计算研究了参数q和m对平均光子数、亚泊松特性和反聚束效应等统计性质的影响 .结果表明 :当q偏离 1较远时 ,二阶q相干函数出现振荡现象 ,其振幅和周期与m无关 ;平均光子数和MandelQq 参数都随着m的增大而急剧增大 ;只要不是q→ 1 。
In this paper, the excited odd q-coherent state a +m qα> o q and excited even q-coherent state a +m qα> e q are constructed. The q and m dependences of mean photon number and sub-Poissonian character and antibunching effect are numerically studied. It is shown that when the q is far from 1, the second-order q-correlation function exhibits oscillating phenomenon, whose amplitude and period are independent of m; but the mean photon number and the Mandel Q q parameter increase greatly as m increases; and the sub-Poissonian character is not equivalent to the antibunching effect unless q→1.
