Abstract

A dual-wavelength thulium-doped fiber laser based on Lyot filter is demonstrated experimentally. A combination of highly nonlinear fiber and a polarizer is applied to induce an intensity-dependent loss mechanism in the laser cavity to suppress homogeneous gain broadening to generate a stable dual output. Upon applying different polarization-maintaining fiber lengths, the wavelength spacing can be changed from 1.8 nm to 0.6 nm. The extinction ratio for the dual lasers is high around 40 dB. The output power is stable with variation of 2.60 dB and 4.69 dB for each channel.
