All-Fiber Bismuth Doped Self-Sweeping Laser
Figure 1: Laser wavelength dynamics The effect of self-induced laser line sweeping (or self-sweeping) was discovered in ruby laser in 1962 [1]. It was considered as an undesirable effect due to a small sweeping range. In fiber lasers the effect with broad sweeping range (more than 10 nm) was observed almost 50 years later [2]. The self-sweeping effect is caused by the formation of dynamical pha...

We report the first demonstration of silica-based thulium-doped fiber amplifier (TDFA) working in the 1.65 – 1.7 μm waveband. Up to 29 dB small signal gain and noise figure as low as 6.5 dB are achieved. OCIS codes: (060.2320) Fiber optics amplifiers and oscillators; (060.2330) Fiber optics communications
متن کاملKerr nonlinearity and dispersion characterization of core-pumped thulium-doped fiber at 2 μm.
A nonlinear coefficient of 3.6-4.1 W-1 km-1 and group velocity dispersion of -20 ps2/km of a commercial core-pumped thulium-doped fiber have been evaluated using degenerate four-wave mixing at 2 μm. The anomalous dispersion behavior of the fiber has been confirmed by linear measurements with an all-fiber Mach-Zehnder interferometer (MZI). Additionally, no pum...
متن کاملSingle-frequency blue laser fiber amplifier.
An all-fiber amplifier for a single-frequency blue laser was demonstrated for the first time, to the best of our knowledge. Over 150 mW continuous-wave single-transverse-mode blue laser output was obtained with a 10 m 1000 ppm thulium-doped fluoride fiber pumped by a 1125 nm fiber laser at a power of 2 W. The output power was limited due to the onset of the competitive lasing at 783 nm. Photoda...
متن کاملKerr nonlinearity of Thulium - doped fiber near 2 m
The nonlinear coefficient and group velocity dispersion of a thulium-doped fiber near 2μm are evaluated via four-wave mixing. Nonlinearity of thulium-doped fiber can be used for the design of doped-fiber lasers in this spectral region.
