A local oscillator (LO) which can correctly decode the spatiotemporally distorted quadrature-squeezed light generated by means of single-pass traveling-wave optical parametric amplification is experimentally demonstrated. Such a matched LO is automatically produced in our squeezed-light generation scheme. With the matched LO 5.8 ± 0.2 dB [(74 ± 1)%] of quadrature squeezing is observed which, to the best of the authors' knowledge, is the highest observed in any traveling-wave squeezing experiment to date.
