1064nm Ultra-Narrow Linewidth ≤ 3 kHz CW Fiber Laser for Acousticsensing utilizes a fiber DFB laser cavity structure to output single-longitudinal-mode, narrow-linewidth continuous-wave laser light in the 1064nm wavelength band. Its spectral linewidth is less than 20kHz, and its output spectral side-mode suppression ratio exceeds 60dB. Higher power versions are also available. Available in module or desktop packages, it is an ideal laser source for applications such as distributed sensing.
● Spectral linewidth ≤ 3 kHz
● All-fiber DFB resonator
● Wavelength-stable, no mode hopping
● LiDAR
● Acoustic sensing, hydrophones
● Fiber optic distributed sensing
