Article Synopsis
  • This study introduces a new erbium-doped fiber laser that uses an innovative MoxWTe-based nonlinear optical modulator to create various pulse types, including bright and dark pulses.
  • Key parameters of the modulator, like modulation depth (7.8%) and saturation intensity (8.6 MW/cm), were measured, demonstrating effective operation at specific output levels of the laser.
  • The findings suggest that adjusting the output energy can enhance the likelihood of generating dark pulses, with potential applications in advancing fiber laser technology.
