| Sumario: | Passively mode-locked fiber lasers provide a compact, cost-effective, and alignment free alternative for generating short optical pulses with high energy, in comparison to their traditional solid-state counterpart. For this reason, in recent years there has been a significant increase in the use of pulsed fiber lasers in various branches of industry such as, materials processing, sensors, medical surgery, as well as scientific research. In this thesis, we present the experimental development of a passively mode-locked double-clad thulium doped fiber laser in a figure of 9 configuration with an all-fiber setup, which can operate in the dissipative soliton resonance (DSR) and rectangular noise-like pulse (NLP) regimes in the 2 micron region. For this, a compact cavity in a figure of 9 configuration is proposed, which consist of a nonlinear amplifying loop mirror (NALM) and a fiber Bragg grating. The NALM is used as an output mirror and acts as the mode-locking element. By properly adjusting the polarization controller, switchable operation between DSR and NLP is generated. The obtained results show that the pulse duration and average output power of the DSR pulse can be tuned from 7.2 to 21.7 ns and from 27 to 73 mW, respectively. The maximum pulse energy is 55 nJ without wave breaking at a pump power of 3.2 W. Additionally, rectangular NLPs with bunch pulse energy of 125 nJ are obtained. |
