We propose neutrino mass spectroscopy using Er3+:Cs2NaYF6 or:Y2O3 crystal placed in hollow of a Bragg fiber as a target system. Unknown neutrino parameters and properties such as the lightest neutrino mass, Majorana/Dirac distinction, and CP violating phases can be explored by measuring scattered photons (γ) along the excitation (and fiber) axis by varying Raman trigger (γ0) directions, in Er3+ de-excitation process from |ei state to |gi state; |ei,|ei+γ0 → |gi+γ +νiν¯j, νi ,i = 1,2,3 being a mass-resolved neutrino state. Rates and required level of QED background rejection are calculated using measured data of the target system.
