Despite its enormous success, astrophysical observations and theoretical considerations indicate, that extensions of the Standard Model of particle physics are required. In the low energy region (m<<1eV) Light shining through a wall (LSW) experiments perform searches for weakly interacting slim particles. ALPS-I is one of those LSW experiments which, for the first time, used a resonant optical cavity to achieve the currently best sensitivity of LSW experiments. Future LSW experiments, like e.g. ALPS-II, will use a second optical resonator to further improve their sensitivities. This is a proposal to develop and test an optical design that allows the required collinear operation of two LSW cavities. Furthermore we will compare two competing readout methods for future LSW experiments by a theoretical study and experiments to identify their fundamental and technical limitations.

尽管它取得了巨大的成功，天体物理学的观测和理论的考虑表明，粒子物理学的标准模型的扩展是必要的。在低能区（m<<1 eV），光穿墙实验（LSW）搜索弱相互作用的细长粒子。ALPS-I是LSW实验之一，首次使用谐振光学腔来实现LSW实验的最佳灵敏度。未来的LSW实验，例如ALPS-II，将使用第二个光学谐振器来进一步提高其灵敏度。这是一个建议，开发和测试的光学设计，允许所需的共线操作的两个LSW腔。此外，我们将比较两个竞争的读出方法，为未来的LSW实验的理论研究和实验，以确定其基本和技术限制。
