We investigated the ~2 μm spectroscopic and lasing performance of Tm³⁺ and Tm³⁺-Ho³⁺ co-doped tungsten tellurite glass single mode fibers with a commercial 800 nm laser diode. The double cladding single mode (SM) fibers were fabricated by using rod-in-tube method. The propagation loss of the fiber was ~2.5 dB/m at 1310 nm. The spectroscopic properties of the fibers were analyzed. A 494 mW laser operating at ~1.9 μm was achieved in a Tm³⁺ doped 20 cm long fiber, the slope efficiency was 26%, and the laser beam quality factor M² was 1.09. A 35 mW ~2.1 μm laser output was also demonstrated in a 7 cm long of Tm³⁺-Ho³⁺ co-doped tungsten tellurite SM fiber.
