Event Details & Abstract: 

The precision of gravitational wave measurements by the Advanced LIGO interferometers is limited by the quantization of light. The current generation of detectors will use squeezed light to reduce this quantum noise.

I will discuss a new method for generating squeezed states of light that uses the optomechanical interaction between light and mirror oscillators. I will discuss optomechanical squeezing broadly and describe experimental efforts to generate optomechanically squeezed states optimized for gravitational wave detection.
