Laser frequency stabilisation by locking to a LISA arm

Sheard, B; Gray, Malcolm; McClelland, David; Shaddock, D


We analyze a technique for suppressing laser frequency noise for the laser interferometer space antenna (LISA) gravitational wave detector. We demonstrate that the laser frequency can be stabilized to a LISA arm by high gain feedback. It is shown that the feedback bandwidth is not limited by the 33 second round-trip propagation time and example frequency controller designs are presented.
