Many demonstrations of the generation and application of squeezed light have recently been made. Progress in its application to spectroscopy,1 however, has been hampered by the lack of tunable sources of squeezed light. Present sources generate squeezing around a fixed frequency, whereas for spectroscopic applications, tunability is desirable. Here, I propose a scheme by which frequency-tunable squeezed light can be generated. I show that it is possible to change a light beam's frequency without affecting its quantum state. Consider the sum frequency process wherein a beam at ω1 is mixed with a pump beam at ω2 to generate the sum ω3 = ω1 + ω2.

Squeezed light generation has come of age. Significant advances on squeezed light generation have been made over the last 30 years—from the initial, conceptual experiment in 1985 till today's top-tuned, application-oriented setups. Here we review the main experimental platforms for generating quadrature squeezed light that have been investigated in the last 30 years.
