Double pass locking and spatial mode locking for gravitational wave detectors

Cusack, B J; Shaddock, Daniel; Slagmolen, Bram; De Vine, Glenn; Gray, Malcolm; McClelland, David


We present novel techniques for overcoming problems relating to the use of high-power lasers in mode cleaner cavities for second generation laser interferometric gravitational wave detectors. Rearranging the optical components into a double pass locking regime can help to protect locking detectors from damage. Modulator thermal lensing can be avoided by using a modulation-free technique such as tilt locking, or its recently developed cousin, flip locking.
