    Area of Science:

    • Optics and Photonics
    • Laser Physics

    Background:

    • Internal-mirror Helium-Neon (He-Ne) lasers exhibit intramode frequency differences when subjected to transverse magnetic fields.
    • Increasing magnetic field strength causes Zeeman frequency shifts that can approach the laser's mode spacing.

    Purpose of the Study:

    • To investigate the phenomenon of mode coupling in He-Ne lasers under magnetic fields.
    • To explore the potential for achieving stable single-mode operation from multimode lasers.
    • To develop a simple frequency stabilization system utilizing the observed intramode frequency difference.

    Main Methods:

    • Application of a transverse magnetic field to an internal-mirror 6328-A He-Ne laser.
    • Systematic variation of magnetic field strength to observe effects on laser modes.
    • Analysis of induced mode coupling and its impact on laser output characteristics.
    • Development and testing of a frequency stabilization system based on intramode frequency differences.

    Main Results:

    • Intramode frequency differences were observed in He-Ne lasers within a transverse magnetic field.
    • Mode coupling was induced by increasing magnetic field strength, leading to Zeeman frequency shifts near the mode spacing.
    • In some multimode lasers, this mode coupling resulted in a collapse to stable single-mode operation.
    • Overall laser power in the output remained unchanged during the transition to single-mode operation.
    • A simple frequency stabilization system demonstrated a frequency variation below 1 part in 10^10.

    Conclusions:

    • Transverse magnetic fields can induce significant intramode frequency differences in He-Ne lasers.
    • Mode coupling, driven by Zeeman shifts, offers a pathway to achieve stable single-mode laser operation from multimode systems.
    • The observed intramode frequency difference provides a basis for a highly precise and simple laser frequency stabilization technique.
