摘要
This paper elaborated the generation of microsecond and nanosecond pulse fiber laser using Mo2Ga2C coating onto DSF. The microsecond pulse commenced at the pump power of 39.826 mW and increased to 81.37 mW with a pulse width of 7.02 mu s-5.92 mu s. Meanwhile, the repetition rate showed measurements between 42.63 kHz to 64.6 kHz corresponding to the maximum pulse energy of 150.15 nJ. Besides that, the nanosecond pulse was generated with an additional length of 200 m for the SMF. The dual wavelength nanosecond pulse began at the pump power of 95.22 mW with a pulse width of 273.7 ns corresponding to the repetition rate of 961.8 kHz. Maximum pulse energy and maximum peak power were 8.75 nJ and 28.15 mW, respectively. The Mo2Ga2C coated DSF acted as the SA and was integrated into an erbium doped fiber laser cavity. The modulation depth of the Mo2Ga2C DSF SA was approximately 7.2 %.
