Abstract: We report a novel single linearly polarized, widely, freely and continuously tunable two wavelengths -doped fiber laser. The laser generates stable arbitrary two wavelengths output between 1003.1 and 1080.7nm peak wavelengths simultaneously with a 346.0mW CW power by using polarization beam splitting (PBS) for separation of two wavelengths. Each lasing line shows a single polarization with a polarization extinction ratio of >20dB under different pump levels. The central and the interval of the two wavelengths can be tuned smoothly and independently in the entire gain region of >70nm of PM -doped single mode fiber. Strongly enhanced polarization-hole burning (PHB) phenomena in polarization maintain (PM) -doped fiber was observed in the tunable two wavelengths -doped fiber laser. [Copyright &y& Elsevier]
