Muonic atoms represent a traditional tool for nuclear spectroscopy by applying atomic-physics techniques. In this contribution we consider a muonic atom exposed to a very strong laser field, where the muon becomes a dynamic probe of nuclear properties. We show that, as a consequence, effects of the finite nuclear mass and size are prominent in calculated high-order harmonic spectra from hydrogenlike muonic atoms [1]. The dependence of these effects on the laser parameters and the charge state of the binding nucleus is discussed [2]. The harmonic cutoff energies from muonic atoms can reach the MeV range, thus providing coherent γ-rays which could by applied to induce nuclear excitation.
