我们报告的压缩脉冲在76 MHz的重复率脉冲零差检测。利用相邻脉冲间的相关系数，实现了对单个脉冲的测量。零差检测器使用低噪声、高速运算放大器构建，其可用带宽为250 MHz。我们观察到2.3分贝的压缩在时域和频域。(C)2008年美国光学学会。
We report pulsed homodyne detection of squeezed pulses at a repetition rate of 76 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 MHz. We observed 2.3 dB of squeezing in both the time and frequency domains.
