Here, we systematically study the optical parameters, energy transfer process and thermal properties of Tm3-doped barium gallo-germanate (BGG)glasses.
BGG glass single mode with high Tm3 (SM)
Fiber is made of rods-in-tube technique.
The doping concentration of Tm3 reached 7.
6 u2009 × 1020 ion/cubic centimeter is the highest level in the reported Tm3-doped bgg sm fiber.

The maximum laser output power of the pulled active fiber is 165 mw, and the slope efficiency is 17%.
Results confirm-
The pulled high Tm3-doped bgg sm fiber has a promising future in applications requiring high gain and high power of short active fiber.
