WebOct 1, 2013 · The thulium doped fiber ions can be considered homogeneously broadened in amplification system and also characterized by the variables N0, N1, N2, N3, N4 and N4 which are used to represent population ions in the 3 H 6, 3 F 4, 3 H 5, 3 H 4, 3 F 2, and 1 G 2 energy levels, respectively. WebThe saturated gain is above 7.0 dB in the 1632-1655 nm waveband, with up to 17.2 dB saturated gain achieved at 1655 nm. The external NFs for saturated signal and small signal were as low as 4.6 dB and 4.4 dB at a wavelength of … WebThulium-doped silica fibers that emit an ultrabroadband luminescence across the 1.65–2.2 μm region may open up another novel approach for approximately 1.7 μm lasing. Admittedly, it is practically difficult to realize 1.7 μm oscillations owing to gain saturation and strong reabsorption in thulium-doped fibers. speedy trial ct
