AB - 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 590MeV ring cyclotron facility of the Paul Scherrer Institute are reviewed. The former experiment determined the antiproton-to-electron mass ratio as Mp¯/me=1836.1526734(15)(Formula Presented). In the latter, a resonant transition (n,)=(17,16)→(17,15)(Formula Presented) of pionic helium at a frequency of ν≈183760GHz was detected. Some future perspectives are briefly described.
