65-fs Pulses at 2 $\mu \text{m}$ in a Compact Tm-Doped All-Fiber Laser by Dispersion and Nonliearity Management
2018
We report a compact ultrafast thulium-doped all-fiber laser delivering 65-fs pulses through nonlinear compression in a dispersion and nonlinearity managed fiber chain. The laser outputs 560-mW, 3.2-nJ pulses with a very broad bandwidth >160 nm at the central wavelength of 1980 nm. Numerical simulation investigates and verifies the formation and evolution of the ultrafast pulse.
