Abstract
ALPS II is a light shining through a wall style experiment that will use the principle of resonant enhancement to boost the conversion and reconversion probabilities of photons to relativistic WISPs. This will require the use of long baseline low-loss optical cavities. Very high power build up factors in the cavities must be achieved in order to reach the design sensitivity of ALPS II. This necessitates a number of different sophisticated optical and control systems to maintain the resonance and ensure maximal coupling between the laser and the cavity. In this paper we report on the results of the characterization of these optical systems with a 20 m cavity and discuss the results in the context of ALPS II.

N1 - Funding Information: Deutsche Forschungsgemeinschaft (DFG) (SFB 676, WI 1643/3-1) The authors would like to thank the other members of the ALPS collaboration for valuable discussions and support and here especially Axel Knabbe and Dieter Trines for their assistance with the vacuum system as well as Reza Hodajerdi and Marian Dürbeck for their work related to the laser system and input optics. This work would not have been possible without the wealth of expertise and hands-on support of the technical infrastructure groups at DESY
