1550nm Single Frequency Nano-second Pulse PMFiber Laser Source Benchtop NL-NSFL-1550-20/1000-50-1/200-PM-B
This laser uses a single-frequency narrow-linewidth laser as a seed source, and cooperates with a high-power gain fiber module to output high-peak and high-energy single-frequency narrow-linewidth laser pulses. The laser wavelength and power are stable, and can be used for coherent lidar and optical fiber sensing. system etc.
[Features]
high pulse energy
Pulse width, repetition frequency and power are adjustable
[Applications]
Laser wind radar
Fiber optic sensing
