Description
Enhance your sensing applications with the precision of the 1550nm Ultra-Narrow Linewidth Fiber Laser. Featuring a rare earth-doped fiber Distributed Feedback (DFB) laser cavity structure, this laser delivers single longitudinal mode output with a spectral linewidth of less than 3kHz and a side mode suppression ratio exceeding 50dB.
Stable, mode-hop-free wavelength operation makes it an ideal choice for laser seed sources, acoustic sensors, hydrophones, fiber distributed sensing, and coherent light communication systems.
