One year of squeezing

The GEO team now has demonstrated that squeezing is a technique that can be permanently used. Over a period of almost one year, squeezing was applied for 90% of the science time, and a total of 205 days!

The average squeezing level achieved during this time was 2.0 dB (Grote, H. et al. in PRL, 2013). We will continue to explore and improve squeezing at GEO in the future.
