Description
Among various upgrade options, high-frequency (kHz) sensitivity is one of the candidates for KAGRA upgrade. With the cryogenic systems, and there is almost no mysterious noises in high-frequency, the Only limitation is the shot noise. In this talk, I will report the status about vOPO (vacuum optical parametric oscillator) test in NAOJ, with preliminarily 7 dB Squeezing (at 2.5 MHz) and nearly 8 dB SQZ (at 100 kHz). Our plans to install KAGRA SQZ Subsystem will also be reported.
