1. Communication field
Narrow linewidth lasers are widely used as light sources and receivers in fiber optic communication systems. In terms of light sources, narrow linewidth lasers can provide high-quality and highly stable optical signals, which can reduce signal distortion and bit error rates. In terms of receivers, narrow linewidth lasers can provide high sensitivity and high-precision light detection, which can enhance the signal detection capabilities of the receiver. In addition, narrow linewidth lasers can be used for functions such as optical filtering and frequency conversion.
2. Spectral analysis field
Narrow linewidth lasers are also widely used in the field of spectral analysis. By choosing the appropriate wavelength and linewidth, narrow linewidth lasers can be used to perform precise spectral analysis and spectral measurements. For example, narrow linewidth lasers can be used to measure optical absorption, optical emission, and molecular spectra in the atmosphere. In addition, narrow linewidth lasers can also be used in fields such as gas sensors and environmental monitoring.
3. Optical measurement field
Narrow linewidth lasers are also widely used in the field of optical measurement. For example, narrow linewidth lasers can be used for measurements such as laser ranging, laser interference, and laser speckle. The accuracy and sensitivity of measurement systems can be improved by using narrow linewidth lasers.
