squeezing and gw detectors
Squeezing and GW detectors
  • Early theoretical work by Braginsky and Caves ~ 1980
  • A few demonstrations on simple interferometers eg Mach Zehnder [1] and polarimeter [2] ~1987
  • In the last few years there has been a revival of interest in squeezing in the GW community as LIGO II is expected to be radiation pressure noise limited (at low frequencies).

squeezing applicability
Squeezing Applicability
  • Realistic (sub)configuration
  • Advanced LIGO signal extraction method (offset locking)
  • All at 1064nm
  • Low frequency squeezing should not be a problem with GW detector
  • Interferometer and squeezing LOCKED
  • Results limited by losses in our isolator~15%
  • But isolator loss less than 0.5% achievable!
