Effect of Bismuth Active Centers Concentration on the Characteristics of Cladding-Pumped Fiber Lasers Near 1450 nm
We report results on cladding-pumped laser based on two low-Ge silica fibers with various bismuth concentration. The maximum efficiency and output power were 3.8% and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\sim 0.38\mathrm{W}$</tex>, respectively. Lasing for >100 hours led to >10% of power degradation.
