Abstract

There is a great interest in the generation of broadband squeezed states with a large noise reduction by a technically simple system, We report here on the first clear broadband (from about dc to about 70 MHz) observation of squeezed states generated by parametric amplification with pulse light excitation¹⁾ in a Ba₂NaNb₅O₁₅ (BNN) crystal, where noncritical type I phase matching is attained.²⁾ A schematic diagram of the experimental configuration is shown in Fig.1.
