    A tunable fiber laser generates a phase-locked frequency comb with adjustable spacing. This self-referenced optical frequency comb is ideal for precise metrology and synchronization applications.

    Area of Science:

    • Optics and Photonics
    • Laser Physics
    • Metrology

    Background:

    • Frequency combs are precise optical rulers.
    • Mode-locked fiber lasers offer compact and stable laser sources.
    • Tunable repetition rates in lasers enable flexible frequency comb spacing.

    Purpose of the Study:

    • To present a phase-locked, self-referenced frequency comb.
    • To demonstrate tunability of the comb's repetition rate.
    • To highlight applications in metrology and laser synchronization.

    Main Methods:

    • Utilizing a mode-locked fiber soliton laser.
    • Implementing a phase-locked loop to stabilize the comb.
    • Scanning the laser's repetition rate from 49.3 MHz to 50.1 MHz.
