A possibility of amplification without population inversion at gamma-ray transition due to excitation of nuclear coherence via coherent optical driving of the electron coupled with nucleus is demonstrated. Hyperfine splitting and isomer shift allow us to get inversionless amplification at gamma-ray transition via nuclear coherence created by the optical driving field.

The extension of optical maser techniques to the γ-ray region is considered. It is shown that under certain conditions induced γ rays can be produced. The condition of criticality rather than that of oscillation is used because a γ-ray maser does not have a resonant structure. The main observable effects are the shortening of lifetimes of some γ excitations and the appearance of two or more coherent γ quanta. It appears to be difficult to prepare samples that will become critical. The principles are applied to a specific example.
