Dark matter (DM) represents one of the most intriguing challenges of modern physics, both for the theoretical predictions and for the experimental setups. The search for the possible DM component candidates regards a wide range of objects and of energy values. In order to detect processes related to very weak interactions, as expected in these cases, it is necessary to improve the performances of the available detectors making them more efficient in terms of energy threshold and mass. Here we present a research activity aimed at the development of a novel type of detector based on laser interrogation of atomic energy levels for species that have been loaded in a solid matrix of a non interacting material at very low temperatures. The laser assisted transitions are only promoted when an incident particle is absorbed in the material, releasing its energy to the embedded atoms. The detection can be obtained via both optical and electronic methods.
