    We developed a new method to create high-repetition-rate short laser pulses from continuous-wave lasers using a passive optical frequency comb. This efficient technique generates pulses as short as 3.3 picoseconds.

    Area of Science:

    • Photonics and Laser Technology
    • Nonlinear Optics
    • Optical Engineering

    Background:

    • Continuous-wave (CW) lasers are fundamental but lack temporal structure for certain applications.
    • Generating ultrashort laser pulses typically requires complex or active mode-locking systems.
    • High repetition rate pulse generation is crucial for applications like optical communications and metrology.

    Purpose of the Study:

    • To demonstrate a novel, passive technique for converting CW laser light into a stable train of short pulses.
    • To achieve high repetition rates and high overall conversion efficiency.
    • To provide a generally applicable system for ultrashort pulse generation.

    Main Methods:

    • Utilized a purely passive coupled-cavity optical frequency comb generator.

    Generation and Coherent Control of Pulsed Quantum Frequency Combs

    Published on: June 8, 2018

  • Employed an electro-optic modulator to control the repetition rate via drive frequency.
  • Adjusted the radio frequency (rf) power applied to the modulator to determine the pulse width.

    • Main Results:

    • Successfully generated a stable train of short laser pulses from a CW laser source.
    • Achieved pulse widths down to 3.3 picoseconds (ps).
    • Observed a high repetition rate of 5.34 gigahertz (GHz) with an overall conversion efficiency of 11%.

    Conclusions:

    • The demonstrated passive coupled-cavity system offers an efficient and generally applicable method for generating high-repetition-rate ultrashort laser pulses.
    • The system's performance, including pulse shape and width, aligns well with theoretical modeling.
    • This technique provides a promising alternative to active mode-locking for specific pulse generation requirements.
