Phys. Rev. Lett. 55, 2409–2412 (1985)Observation of Squeezed States Generated by Four-Wave Mixing in an Optical CavitySee Also: Erratum Received 27 August 1985; published in the issue dated 25 November 1985 Squeezed states of the electromagnetic field have been generated by nondegenerate four-wave mixing due to Na atoms in an optical cavity. The optical noise in the cavity, comprised of primarily vacuum fluctuations and a small component of spontaneous emission from the pumped Na atoms, is amplified in one quadrature of the optical field and deamplified in the other quadrature. These quadrature components are measured with a balanced homodyne detector. The total noise level in the deamplified quadrature drops below the vacuum noise level. © 1985 The American Physical Society URL:
