Starting from a fully quantized Hamiltonian for an ensemble of identical emitters coupled to the modes of an optical cavity, we determine analytically regimes of thermal, collective anti-bunching and laser emission that depend explicitly on the number of emitters. The lasing regime is reached for a number of emitters above a critical number-which depends on the light-matter coupling, detuning, and the dissipation rates-via a universal transition from thermal emission to collective anti-bunching to lasing as the pump increases. Cases where the second order intensity correlation fails to predict laser action are also presented.
从一个与光学腔模式耦合的相同发射器集合的完全量子化哈密顿量出发，我们通过解析确定了热发射、集体反聚束和激光发射的区域，这些区域明确依赖于发射器的数量。当发射器数量超过一个临界数量时达到激光发射区域，该临界数量取决于光与物质的耦合、失谐以及耗散率，随着泵浦增加，通过从热发射到集体反聚束再到激光发射的普遍转变实现。我们还给出了二阶强度关联无法预测激光作用的情况。
