    "abstract": "A general theory is presented for the photodetection statistics of coherent\nradiation that has been amplified by a disordered medium. The beating of the\ncoherent radiation with the spontaneous emission increases the noise above the\nshot-noise level. The excess noise is expressed in terms of the transmission\nand reflection matrices of the medium, and evaluated using the methods of\nrandom-matrix theory. Inter-mode scattering between $N$ propagating modes\nincreases the noise figure by up to a factor of $N$, as one approaches the\nlaser threshold. Results are contrasted with those for an absorbing medium.",
