Abstract

In order to meet the needs of the interferometry fiber optic hydrophone for high-power strong coherent laser source, a narrow linewidth distributed feedback fiber laser (DFB-FL) with high-power 16-wavelength ITU channels was developed by the MOPA amplification technology. The output power of single wavelength laser is more than 10 mw, the laser linewidth is less than 2 kHz, the relative intensity noise (RIN) is less than -105 dB/Hz. By comparing with other narrow linewidth fiber lasers from NKT compony and NP Photonics compony, the performance of the linewidth of the developed laser reaches the international advanced level. It can be used as strong coherent laser source of fiber optic hydrophone and other hydroacoustic detection.
