Development of precise nanosecond and picosecond dye lasers for spectroscopy of antiprotonic atoms

Abstract

Two laser systems were developed by the ASACUSA collaboration of CERN to carry out spectroscopy experiments on antiprotonic atoms. One of these was a continuous-wave pulse-amplified dye laser which was frequency-stabilized to a femtosecond frequency comb. The other generated 700-ps-long laser pulses of wavelengths λ = 266 and 532 nm using two stimulated Brillouin scattering cells filled with water.
