Abstract

We report pulsed homodyne detection of squeezed pulses at a repetition rate of $76\mathrm{MHz}$. Measurement of individual pulses, which were interrogated by the correlation coefficient between adjacent pulses, was realized. A homodyne detector was constructed using a low-noise, high-speed operational amplifier; it had a usable bandwidth of $250\mathrm{MHz}$. We observed $2.3\mathrm{dB}$ of squeezing in both the time and frequency domains.
