Area of Science:

  • Photonics and Laser Technology
  • Materials Science

Background:

  • Erbium-doped fiber lasers (EDFLs) are crucial for optical communications.
  • Developing novel saturable absorbers (SAs) is key to advancing laser performance.
  • Titanium disulfide (TiS2) is explored for its unique optical properties.

Purpose of the Study:

  • To investigate the performance of TiS2 as a saturable absorber in EDFLs.

Main Methods:

  • Fabrication of a TiS2-based saturable absorber.
  • Integration of the TiS2 SA into an Er-doped fiber laser cavity.
  • Experimental optimization of laser cavity parameters (length, loss).
  • Characterization of mode-locked and Q-switched pulse properties (wavelength, pulse width, energy, repetition rate).

Main Results:

  • Successfully generated passively mode-locked EDFLs with pulses centered at 1531.69 nm and a minimum pulse width of 2.36 ps.
  • Achieved Q-switched operation with a maximum pulse energy of 67.2 nJ and a minimum pulse duration of 2.34 µs.
  • Demonstrated a tunable repetition rate for Q-switched pulses from 13.17 kHz to 48.45 kHz.

Conclusions:

  • TiS2 exhibits excellent nonlinear absorption characteristics.
  • TiS2 shows significant potential as a saturable absorber for ultra-fast photonics devices.
  • The developed TiS2-based EDFLs offer versatile performance for various applications.
