1. Description:
The single-frequency narrow linewidth fiber laser uses an ultra-narrow linewidth external cavity semiconductor laser chip, outputs a single longitudinal mode laser with a wavelength of 1550nm, and a spectral linewidth of less than 100kHz. It is coupled to a single-mode or polarization-maintaining fiber and provides module or desktop packaging. It is a cost-effective laser source that can be used for distributed sensing.
2. Features:
Spectral line width ≤100KHz;
DFB laser chip;
Wavelength stable without mode hopping.
3. Applications:
LiDAR;
Acoustic sensors, hydrophones;
Fiber Optic Distributed Sensing.
