Paper Abstract

The Gouy phase is an important phase, however rather poorly understood. It has been shown recently that it can be used to control the frequency of a ring laser and can help in achieving a control over mode-locking problem of ring laser gyro. It is demonstrated now that with the help of the Gouy phase one discovers further characterization of a laser involving cascaded optics in terms of what may be called longitudinal Gouy phase branches. On such a Gouy phase branch one can tune the laser in a manner described elsewhere. It is noted that the longitudinal Gouy-phase-branches play significant role in cascaded optical systems as well as have potential characterization feature in several ring configurations that get naturally selected in a random lasing medium. The concept is further clarified with Collins chart diagrams of several cascaded optics lasers.
