Stabilized dual-wavelength erbium-doped dual-ring fiber laser.
A stable dual-wavelength erbium-doped fiber (EDF) compound ring laser using a double-ring filter (DRF) is proposed and demonstrated experimentally. By using a ring filter incorporated within the ring cavity, the fiber laser can lase two wavelengths simultaneously. The dual-wavelength output exhibits a good performance having the optical side-mode suppression ratios (SMSRs) of 45.3 and 46.3 dB a...
متن کاملSwitchable multi-wavelength Tm-doped mode-locked fiber laser.
We propose and demonstrate for the first time a switchable tri-wavelength Tm-doped ultra-fast fiber laser based on nonlinear polarization evolution (NPE) technique. The NPE effect induces wavelength-dependent loss in the cavity that changes the homogeneous broadening of the effective gain to become inhomogeneous. This inhomogeneous effective gain spectral profile enables the multi-wavelength mo...
متن کاملTransient response of a passively mode-locked Er-doped fiber ring laser
In this study, we report on the transient response of a passively mode-locked erbium fiber ring laser as studied by switching the optical pumping of the erbium doped fiber on and off. We confirm that the laser can maintain its mode-locking state even while the pump is modulated, and describe the laser behavior and its typical transient response upon abrupt changes in the intensity of the optica...
متن کاملTunable and switchable dual-wavelength Tm-doped mode-locked fiber laser by nonlinear polarization evolution.
We propose and demonstrate a tunable and switchable dual-wavelength ultra-fast Tm-doped fiber laser. The tunability is based on nonlinear polarization evolution (NPE) technique in a passively mode-locked laser cavity. The NPE effect induces wavelength-dependent loss in the cavity to effectively alleviate mode competition and enables the multiwavelength mode locking. The laser exhibits tunable d...
متن کاملHybrid Mode Locked Fiber Ring Laser
Mode locked pulse generation has been reported using both active and passive mode locking schemes. Active mode locking technique has been proven to be an effective way to generate high-repetition-rate pulses by incorporating a modulator inside the laser cavity. Compared to actively mode locked lasers, passively mode locked lasers can generate pulse train at ultrashort pulse width but with relat...
