Abstract

An erbium-doped fiber laser based on nonlinear polarization rotation (NPR) mode-locking is proposed. On account of the multi-mode interference filtering effect introduced by the laser cavity multi-mode fiber, by adjusting the cavity polarization controllers, the laser generates dual-wavelengths of 1533.48 nm/1547.61 nm, 1549.16 nm/1561.94 nm, 1533.14 nm/1562.96 nm, and triple-wavelengths of 1533.43 nm, 1548.46 nm and 1562.68 nm, corresponding to 388.95 kHz, 388.93 kHz and 388.91 kHz, respectively. The compact structure of the system has potential applications in spectroscopy, optical communication, optical sensing and other fields.
