摘要
Gain and emission spectrum characteristics of Tm^(3+)-doped telluride glass fibers pumped with 465 nm lasers are analyzed. The rate and power propagation equation groups of the fibers are solved numerically and the effects of the fiber parameters including active ion concentration, length and pump power on the gain spectra and amplified spontaneous emission(ASE) spectra are analyzed. The results show that with a pump parameter of 465 nm/200 mW, a doping concentration of 2.5 × 10^(25) ion/m^3 and a fiber length of 16 m, the gain and ASE spectra can cover from 1.100 to 1.900 μm, and the gain and ASE power peaks can reach 52 dB and 8 mW, respectively.
