    Summary

    Spontaneous emission causes laser beam centroids to fluctuate. This occurs when the laser medium emits light into unintended higher-order modes, affecting beam stability.

    Area of Science:

    • Laser physics
    • Quantum optics
    • Photonics

    Background:

    • Single-transverse-mode lasers are crucial for precision applications.
    • Beam centroid fluctuation can degrade laser performance.

    Purpose of the Study:

    • To investigate the cause of laser beam centroid fluctuations.
    • To understand the role of spontaneous emission in mode coupling.

    Main Methods:

    • Analysis of spontaneous emission processes in laser cavities.
    • Theoretical modeling of transverse mode excitation.

    Main Results:

    • Spontaneous emission into higher-order transverse modes is identified as the primary cause of centroid drift.
    • The rate of spontaneous emission directly correlates with the magnitude of centroid fluctuation.
