摘要： In this paper, n-photon correlated-spontaneous-emission lasers (GEL's) are studied via the quantum theory of Scully-Lamb. It is shown that inversionless lazing can be exhibited; and phase squeezing can be produced in the inversionless region when the laser intensity is smaller than a certain value. The unified approach to n-photon CEL's is given and the properties between n-photon CEL's (n≥3) and CEL's of n = 1,2 are compared.
