At 10 cm in length, the saturable absorber generated Q-switched fiber laser at a pump power threshold of 39.6 mW and a central wavelength of 1601.93 nm. Beyond 53.3 mW, a spectrum with a central wavelength at 1602.00 nm was generated. On the other hand, the pulse repetition rate was obtained from 3.44 to 7.47 kHz whereas the pulse width reduces from 100.2 to 58.6 �s for pump power ranges from 39.6 to 53.3 mW. Within this range, the pulse energy is attained between 0.2600 and 0.2843 �J, at a laser power slope efficiency of 6.94%. The constantly operated Q-switched fiber laser over 50 min observation time at 53.3 mW pump power ensures the feasibility of this pulse laser source as a practical device. � 2019 Elsevier Ltd Final 2023-05-29T07:22:52Z 2023-05-29T07:22:52Z 2019 Article 10.1016/j.optlastec.2019.105615 2-s2.0-85067172491 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85067172491&doi=10.1016%2fj.optlastec.2019.105615&partnerID=40&md5=c3a5a9301fc7202887bf898dfcc547b5 https://irepository.uniten.edu.my/handle/123456789/24341 119 105615 All Open Access, Green Elsevier Ltd Scopus |
