    Laser spectroscopy of muonic hydrogen (μp) is an ideal platform to probe the proton structure. 45m
    
    At the Paul Scherrer Institute, the CREMA collaboration aims to measure the ground-state hyperfine splitting (1S HFS) with a relative accuracy of 10−6 to infer the proton structure contribution (two photon exchange correction) with a relative accuracy of 10−4. For this measurement, we develop a pulsed laser system with the aim of delivering 3 mJ pulses at a wavelength of 6.8 µm stochastically triggered by the arrival of muons. In this talk, I will explain the measurement principle and the present state of our experiment.
