DK Photonics 1550nm Single Frequency Nano-second Pulse Fiber Laser uses a single frequency narrow linewidth laser as the seed source, combined 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 in coherent laser radar, fiber sensing systems, etc.
