Progress towards development of efficient Bi-doped fiber lasers and amplifiers
Development of lasers and amplifiers in new wavelength regions have been the research interest for decades. Bi-doped fibers paved the way to develop lasers and amplifiers in 1150-1500nm wavelength range owing to its broad luminescence characteristics. Bi-doped aluminosilicate, phosphosilicate and germanosilicate fibers have shown luminescence around 1150nm, 1300nm and 1450nm respectively. Here, we present the fabrication of Bi-doped fibers with aluminosilicate and phosphosilicate hosts by the MCVD-solution doping technique. These fibers were characterised for absorption and unsaturable loss. The obtained results were used to select appropriate pump wavelength for laser and amplifier development. A Bi-doped aluminosilicate fiber amplifier has been demonstrated with a maximum gain of 8dB at 1180nm. In addition, a 22mW Bi-doped phosphosilicate fiber laser operating at 1360nm has been reported with a laser efficiency of 11% by direct diode pumping at 1267nm.

Abstract
Development of lasers and amplifiers in new wavelength regions have been the research interest for decades. Bi-doped fibers paved the way to develop lasers and amplifiers in 1150-1500nm wavelength range owing to its broad luminescence characteristics. Bi-doped aluminosilicate, phosphosilicate and germanosilicate fibers have shown luminescence around 1150nm, 1300nm and 1450nm respectively. Here, we present the fabrication of Bi-doped fibers with aluminosilicate and phosphosilicate hosts by the MCVD-solution doping technique. These fibers were characterised for absorption and unsaturable loss. The obtained results were used to select appropriate pump wavelength for laser and amplifier development. A Bi-doped aluminosilicate fiber amplifier has been demonstrated with a maximum gain of 8dB at 1180nm. In addition, a 22mW Bi-doped phosphosilicate fiber laser operating at 1360nm has been reported with a laser efficiency of 11% by direct diode pumping at 1267nm.
