Ultra-low noise laser Precilasers' 1.5 µm low phase noise erbium-doped fiber DFB laser adopts active feedback control technology, which can significantly suppress the phase noise in the key frequency band of 1 Hz–1 kHz. It features a hertz-level ultra-narrow linewidth and ultra-low phase noise, and can stably output an optical power of >10 mW within the wide tunable wavelength range of 1530–1570 nm, providing a high-performance light source for high-precision coherent sensing, quantum communication and other scenarios.
