LIPSS status and LIPSS-2 future experiments

The LIght Pseudoscalar and Scalar Search (LIPSS) experiment was the first dark matter experiment to use a photon beam from a high average power free-electron laser (FEL). LIPSS employed the ``Light Shining through a Wall'' (LSW) technique. Results from these laboratory dark matter searches established new boundaries for six possible dark matter particles. In addition, the experimental set-up can be modified for dark energy particle searches using the ``Particles in a Jar'' technique. The LIPSS set-up will be summarized and a brief description of other DM/DE search possibilities (LIPSS-2) with the FEL facility will be discussed.
