    Multiple frequency conversion processes were observed in a resonant harmonic generator. This leads to new emission wavelengths and stable, tunable output, acting as an optical limiter near degeneracy.

    Area of Science:

    • Optics and Photonics
    • Nonlinear Optics
    • Laser Physics

    Background:

    • Externally resonant harmonic generators are crucial for producing specific light wavelengths.
    • Understanding complex frequency-conversion dynamics is key to optimizing laser systems.

    Purpose of the Study:

    • To investigate the coexistence of multiple frequency-conversion processes in a resonant harmonic generator.
    • To characterize the generated wavelengths, stability, and tunability.
    • To explore the device's behavior as an optical limiter.

    Main Methods:

    • Utilized an externally resonant second-harmonic generator.
    • Observed subharmonic-pumped parametric oscillation generating signal and idler waves.
    • Investigated sum-frequency mixing among resonant waves.

    Main Results:

    • Demonstrated coexisting frequency-conversion processes, including parametric oscillation and sum-frequency mixing.
    • Observed additional emission wavelengths around the harmonic (532 nm).
    • Achieved high frequency stability (4 h mode-hop-free) and continuous tunability (2 GHz).
    • Observed optical limiting behavior for the harmonic wave near degeneracy.

    Conclusions:

    • Multiple nonlinear optical processes can coexist in resonant harmonic generators.
    • The system offers stable, tunable light generation with potential optical limiting applications.
    • Further research can explore optimizing these complex interactions for advanced laser sources.
