Abstract
We study a three-level atom assemble interacting with a pump field and a quantum probe field, and derive the Langevin quantum noise operators and quantum noise spectrum due to vacuum fluctuations via quantum theory. We calculate the output noise spectrum of active Raman scattering field through the medium when introducing one nonclassical squeezing field.
