Vacuum squeezed light producing device and vacuum squeezed light producing method

Abstract

A squeezed vacuum producing device includes a two-wavelength optical pulse light source with a coaxial path which synchronizes two optical pulses configured with a first optical pulse having an optical frequency f1 and a second optical pulse having an optical frequency f2 (f1≠f2). The squeezed vacuum producing device outputs a two-wavelength optical pulse in a state where a relative phase between the first optical pulse and the second optical pulse does not fluctuate Furthermore, a squeezed vacuum producing unit that includes a nonlinear optical medium, inputs the two-wavelength optical pulse output by the two-wavelength optical pulse light source to the nonlinear optical medium, generates squeezed vacuum having an optical frequency fo (fo≠f1 and fo≠f2) by a nonlinear optical effect, and outputs the squeezed vacuum.
