摘      要：We demonstrate an efficient fiber laser operating at 1901.6 nm using a newly developed thulium bismuth co-doped fiber(TBF)with dual pumping at 792 nm and 1552 *** fiber was fabricated using modified chemical vapor deposition and solution doping *** dopant concentrations(wt%)and compositions inside the core are 0.15 Bi_(2)O_(3),0.3 Tm_(2)O_(3),1.0 Al_(2)O_(3) and 12.0 GeO_(2).The TBF laser operates at 1901.6 nm with a lasing efficiency of 33.2%and pump power threshold of 85 mW using a 2-m-long TBF in a linear cavity with two fiber Bragg gratings(FBGs).The high efficiency is attributed to the use of additional 1552 nm pump to complement 792 nm *** maximum output power of 225 mW is achieved at the pump power of 820 mW with the optimum length of 2 m.
