Abstract
THE recent interest in the development of infra-red and optical maser systems has involved a number of different basic principles1–3. This communication is concerned with an alternative concept which utilizes the Stokes's shift associated with absorption and emission bands created by point defects in solids. Preliminary calculations indicate that such a device can be made to operate.
