    Area of Science:

    • Nonlinear Optics
    • Laser Physics
    • Quantum Optics

    Background:

    • Picosecond optical parametric oscillators (OPOs) are crucial for generating tunable ultrashort laser pulses.
    • Achieving stable, phase-locked operation in ultrafast OPOs, especially in the degenerate regime, remains a challenge.

    Purpose of the Study:

    • To demonstrate a degenerate self-phase-locked picosecond OPO with high average power and spectral stability.
    • To investigate the benefits of phase-locking for stabilizing OPO output characteristics.

    Main Methods:

    • Utilized a mode-locked Yb-fiber laser at 1064 nm for synchronous pumping.
    • Employed a 50-mm-long MgO:PPLN crystal for type-0 phase matching.
    • Implemented f-2f interferometry and radio frequency measurements for validation.

    Main Results:

    • Achieved broadband degenerate output near 2 µm with 2.8 W average power at an 80 MHz repetition rate.
    • Generated phase-locked pulses of ~21 ps duration with a ~202 nm bandwidth centered at 2128 nm.
    • Demonstrated excellent passive long-term power and spectral stability with high spatial beam quality.

    Conclusions:

    • This work presents the first degenerate self-phase-locked picosecond OPO.
    • The developed OPO achieves the highest average power reported for a phase-locked ultrafast OPO to date.
    • Self-phase-locking ensures spectral and power stabilization at degeneracy, validated by advanced measurement techniques.
