Squeezing and anti-squeezing measurement with CCFC

[Aritomi, Michael]

We measured squeezing and anti-squeezing for different green power with CCFC. We changed the green power from 10mW to 30mW with 5mW step. The OPO temperature and p pol PLL frequency are summarized in elog2577.

For green power larger than 40mW, we couldn't find squeezing (~ -130dBm at minimum) and the noise level suddenly changed from -130dBm to -110dBm...

The result is shown in the attached figure. Since we couldn't inject large green power, the phase noise information cannot be extracted.
