Overview

Experimental findings reveal wavelength tuning of continuous-wave and Q-switched mode locking in fiber lasers, highlighting their functional versatility.

Key Points

  • Continuous wavelength tuning of over 20 nm for both continuous-wave and Q-switched mode locking is achieved.
  • The nonlinear amplifying loop mirror serves as an artificial saturable absorber while enabling tunable spectral filtering.
  • Adjusting pump power and polarization controllers allows for alternate generation of both pulse types.
  • These wavelength-tunable outputs have significant implications for applications like laser micromachining.
