Blog Article
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 Features:
Ultra-precise frequency stability
Low phase noise and high coherence length
Used in atomic clocks, LiDAR, and quantum optics
These lasers are critical in scientific research, telecommunications, and metrology, where even minor frequency fluctuations can impact performance.
