We developed a phase-coherent laser system for atomic coherence experiments. This system enables continuous frequency scanning over tens of gigahertz while maintaining phase lock, crucial for applications like electromagnetically induced transparency.

Area of Science:

  • Atomic Physics
  • Quantum Optics
  • Laser Spectroscopy

Background:

  • Coherent atomic media require precisely controlled laser systems for advanced experiments.
  • Maintaining phase coherence between multiple lasers over broad frequency ranges is technically challenging.
  • Applications like electromagnetically induced transparency (EIT) demand stable, tunable laser sources.

Purpose of the Study:

  • To develop and characterize a phase-coherent laser system for experiments with coherently prepared atomic media.
  • To demonstrate a technique for continuous frequency scanning of phase-locked lasers over tens of gigahertz.
  • To showcase the system's utility in achieving significant absorption reduction via EIT.

Main Methods:

  • Utilized three external-cavity diode lasers operating around 795 nm.

  • Implemented a sample-and-hold circuit with electronic reset for continuous frequency scanning.
  • Employed an optical phase-locked loop (OPLL) to phase-lock two high-power lasers to a low-power reference laser.
  • Measured residual phase noise to quantify system stability.

    • Main Results:

    • Achieved continuous relative frequency scanning over tens of gigahertz with maintained phase lock.
    • Measured a residual phase noise of less than 0.04 rad(2), indicating high phase coherence.
    • Successfully demonstrated electromagnetically induced transparency (EIT) in a rubidium vapor cell.
    • Obtained a 92% reduction in the absorption coefficient using the developed laser system.

    Conclusions:

    • The developed phase-coherent laser system provides a stable and tunable platform for atomic coherence experiments.
    • The implemented frequency scanning technique is effective for broad-range phase-locked operation.
    • The system's performance is suitable for advanced quantum optics applications, as evidenced by the significant EIT-based absorption reduction.
