We review some lasers developed by the ASACUSA collaboration of CERN, to carry out spectroscopy of antiprotonic helium atoms. These lasers were based on the technique of continuous-wave injection seeding of pulsed lasers. The laser output covered the wavelength regions 264–1154 nm, with peak powers of ~ 1 MW and spectral resolutions of 6–40 MHz. The devices were recently used to measure the transition frequencies of antiprotonic helium atoms to a fractional precision of several parts in ~ 109.
