Achieving a narrow spectral linewidth requires careful laser design and stabilization techniques. Common methods include: External Cavity Feedback: Using gratings or optical feedback to refine the laser’s wavelength. Frequency Stabilization: Locking the laser frequency to a reference cavity or atomic transition. Low-Noise Pu
Narrow linewidth lasers play a vital role in advanced technologies due to their exceptional frequency stability. Here are some key applications: Optical Communications: Used in coherent optical fiber communications to minimize signal distortion. Atomic Clocks & Metrology: Enable ultra-precise timekeeping and frequency standards.
Narrow linewidth lasers are specialized light sources that emit laser beams with extremely small spectral widths, often measured in kilohertz (kHz) or even hertz (Hz). Unlike broadband lasers, these lasers maintain a highly stable and precise frequency, making them essential for applications requiring high coherence and low phase noise. Key Featur
