Abstract:

The frequency dependent squeezing experiment is carried on for the quantum noise reduction of KAGRA. This experiment is mainly divided into two parts. One is the generation of frequency independent squeezing. The other is the operation of the filter cavity. And the combination of them will give us frequency dependent squeezing. We finished the separate construction of them. We achieved the generation of 4dB squeezing at 200kHz.

In this poster I will report the current status of the experiment and the most recent results will be presented.
