Practical and High SNR Mid-Infrared Dual-Comb Spectroscopy Based on Bidirectional Dual-Comb Er Fiber Laser
Practical mid-infrared dual-comb spectroscopy based on a bidirectional-typed dual-comb fiber laser is demonstrated. Real-time and long-term coherent averaging achieve highly sensitive greenhouse gas spectroscopy with absolute wavelength around 4 μm regions without complex tight-locking system. © 2024 The Author(s)
