AB - <jats:p> The results of laser spectroscopy experiments of antiprotonic helium atoms carried out at the Antiproton Decelerator of CERN, and pionic helium atoms measured at the 590[Formula: see text]MeV ring cyclotron facility of the Paul Scherrer Institute are reviewed. The former experiment determined the antiproton-to-electron mass ratio as [Formula: see text]. In the latter, a resonant transition [Formula: see text] of pionic helium at a frequency of [Formula: see text][Formula: see text]GHz was detected. Some future perspectives are briefly described. </jats:p>
