GENERATION OF PICOSECOND SQUEEZED PULSES USING AN ALL-SOLID-STATE CW MODE-LOCKED SOURCE

We have produced squeezed states of light using a degenerate optical p arametric amplifier pumped by an all-solid-state cw mode-locked laser source. The process resulted in squeezed light pulses of less than 3 p s in duration. Up to 0.7 dB of amplitude-squeezed light at 1047 nn and 0.5 dB of noise reduction in vacuum were observed directly. The infer red squeezing level in both cases, after all propagation losses in the detection system and the effects of spatial and temporal mode overlap had been taken into account, was 1.8 dB.
