We demonstrate the first operation and preliminary characterization of a dual core double-clad fiber laser where the laser operates in a coaxially doped thulium outer core region and in-turn resonantly pumps a laser with a holmium doped inner core. The fiber laser is 790nm pumped producing up to 1.5 W near 2.1μm.
