Optoelectronic Hybrid Oscillating-Based Feedback-Feedforward Scheme for Laser Linewidth Compression
We demonstrate a laser linewidth compression system with feedback and feedforward, based on optoelectronic hybrid oscillation, which compresses the linewidth to 29 Hz with <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$-78 \text{dBc} / \text{Hz}$</tex> phase noise at 1 kHz offset, enabling high-precision applications.
