Stability properties of the monochromatic spectrum in a double-cavity laser

We discuss the process by which the spectrum of monochromatic modes of the laser in a double-cavity laser changes from that proper to a short cavity into that proper to a long cavity as the reflectivity of the “external” mirror is varied from [Formula Presented] to [Formula Presented] This work is t...
