We compare the laser performance of a low Tm3+-doped silica fiber laser as pumped at 800 nm to one as pumped at 1620 nm. Using 800 nm non-resonant (3H6→3H4) pumping, 5.5 W of 1940 nm at 32% optical slope efficiency was demonstrated while 1620 nm resonant pumping (3H6→3F4) yielded 13 W with 55% slope efficiency from the same Tm-doped fiber. We also include experimental results our first demonstration of 1620 nm resonant pumping of a Tm-doped fiber with 15.5 W and 67% slope efficiency using an optimized fiber coupled source.
