Microcavity lasers with semiconductor quantum dots as active material have attracted considerable attention recently. We present a theoretical study of the first‐order coherence of such novel light sources. The correlation function $g^{(1)} ({\tau} )$ and the corresponding coherence time are computed including photon–carrier and photon–photon correlations with respect to the delay time τ up to the quadruplet level of the cluster expansion scheme. A comparison of the different levels of the cluster expansion is provided.
