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!
