A simple, purely optical approach to produce, in a ring Ti:Al2O3 laser, a pulsed unidirectional generation, spectrally fixed at a reference atomic absorption line is described. The control relies on the unbalance between two opposite, passive, wavelength-scanned self-injections that is produced by the absorption at the reference line. It is shown both experimentally and theoretically that: (i) the emitted spectrum is centered at the absorption maximum and (ii) due to the nonlinear character of the process the spectrum is narrowed several times compared with an absorption linewidth. © 2000 American Institute of Physics.
