Laser emissions at 1.6–1.7 μm band have captured considerable attention in recent years. However, limited by the available emission spectrum of typical rare-earth-ion doped gain fibers, it is extremely difficult to realize highly stable laser output in this wavelength region with a simultaneous high spectral purity and high output power. To address these problems, a cost-effective robust random fiber lasing scheme is proposed to generate the high-power and high-spectral-purity laser output at 1.69 μm. The maximum output power is 7.55 W and the spectral contrast between the output lasing and the pump is as high as 24.3 dB. Both the short-time temporal characteristics and the long-time output power fluctuations are measured, which shows excellent stability and robustness of the laser configuration. This work provides an alternative approach to realize high-performance 1.6–1.7 μm band lasing output which is of particular significance for potential applications.
