Abstract

Two lasers can be arranged in the geometry shown. The bleachable absorber can either be made part of the laser cavities or not, depending on whether or not the surfaces facing the lasers are coated with antireflecting coatings.

And Device Using Two Lasers and a Bleachable Absorber

Two lasers can be arranged in the geometry shown. The bleachable absorber can either be made part of the laser cavities or not, depending on whether or not the surfaces facing the lasers are coated with antireflecting coatings.

In the case where the bleachable absorber is part of the laser cavities, the level of pumping the lasers can be made such that, if only one is operating, the absorber is not sufficiently bleached for the laser to reach threshold. If both are operating, the absorber is sufficiently bleached for both to lase. If the bleachable absorber is not part of the laser's cavities, the outputs 1' and 2' only register if both are on.
