Extruded Microstructured Fiber Lasers

We present the first fiber laser fabricated from an extruded microstructured preform. This laser is also, to the best of our knowledge, the first microstructured tellurite glass fiber laser. The threshold and efficiency of the 980-nm pumped, 1.5-μm erbium-doped tellurite laser were measured to be 1....

Description
Summary:We present the first fiber laser fabricated from an extruded microstructured preform. This laser is also, to the best of our knowledge, the first microstructured tellurite glass fiber laser. The threshold and efficiency of the 980-nm pumped, 1.5-μm erbium-doped tellurite laser were measured to be 1.5 mW and 13%, respectively.
