    "abstract": "We study a generalized notion of two-mode squeezing for the Stokes and\nanti-Stokes fields in a model of a cavity Raman laser, which leads to a\nsignificant reduction in decoherence or quantum noise. The model comprises a\nloss-less cavity with classical pump, unsaturated medium and arbitrary\nhomogeneous broadening and dispersion. Allowing for arbitrary linear\ncombinations of the two modes in the definition of quadrature variables, we\nfind that there always exists a combination of the two output modes which\nexhibits quadrature squeezing with noise reduction below the vacuum level. The\nnumber of noise photons for this combination mode is proportional to the square\nroot of the number of Stokes noise photons.",
