Dissipative soliton resonance in a simple linear cavity Tm³⁺-doped double clad fiber laser with dispersion management

Abstract

We report on the investigation of large energy dissipative soliton resonance (DSR) pulse generation in a simple linear cavity Tm 3+ -doped fiber laser (TDFL), by using semiconductor saturable absorption mirror as saturable absorber. This DSR TDFL is implemented by utilizing ultra-high numerical aperture 4 (UHNA4) fiber for dispersion compensation. With further dispersion management, the DSR TDFL can generate an average output power of 242 mW with corresponding pulse energy of ~61 nJ. Moreover, the soliton molecules mode-locked operation has also been demonstrated in this TDFL. Our results can provide an easily accessible way to develop large energy TDFLs.

“…The GVD of SMF-28 was -0.0663 ps 2 m −1 at 1944 nm and −0.0672 ps 2 m −1 at 1950 nm. The calculated GVDs for the active fibers (TDF and THDF) and SMF−28 are in agreement with previous study 82 – 84 . By computing the , the net cavity dispersion of −1.28 ps 2 and −1.17 ps 2 were obtained for TDFL and THDFL, respectively, indicating that the operation of both lasers were in the anomalous dispersion regime.…”
