Abstract

We report pulsed homodyne detection of squeezed pulses at a repetition rate of 76MHz. 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 250MHz. We observed 2.3dB of squeezing in both the time and frequency domains.
