Generation of dissipative soliton resonance and pulse burst in an Nd-doped all-fiber mode-locked laser operating at 910 nm

Macro-bending of optical fiber makes bending loss increase at longer wavelength, so the 1.06 mu m laser can be suppressed without affecting 0.9 mu m laser emission. In this paper, it is implemented as a new approach to suppress 1.06 mu m laser emission and produce 0.9 mu m laser in an Nd-doped single-mode all-fiber mode-locked laser. Dissipative soliton resonance (DSR) pulses with pulse width increasing from 1.46 ns to 6.33 ns are generated in the Nd-doped all-fiber mode-locked laser operating at 0.9 mu m. Besides that, the 0.9 mu m pulse burst with pulse number of 1-3 is generated.

Automated summary

This paper presents a new approach to suppress 1.06 mu m laser emission and produce 0.9 mu m laser using macro-bending of optical fiber. Experimental results demonstrate the generation of dissipative soliton resonance (DSR) pulses at 0.9 mu m with varying pulse widths, as well as pulse bursts at 0.9 mu m.
