We present the application of polarization-maintaining thulium-doped fiber (PM-TDF) as a saturable absorber in an erbium-ytterbium-doped fiber laser. A commercial erbium-ytterbium-doped fiber amplifier (EYDFA) was employed in a ring cavity laser configuration with a sub-cavity that allowed bidirecti...
