An experimental demonstration of a 1/1.5 mu m dual-band mode-locked fiber laser is presented. The laser utilizes a unique architecture where the 1 mu m and 1.5 mu m signals are generated independently in shared cavities, with mode-locking achieved through nonlinear polarization evolution and cross-phase modulation. Synchronized dual-band mode-locking operation is successfully achieved using the laser.
A 1/1.5 mu m dual-band mode-locked fiber laser is experimentally demonstrated. The laser is based upon an architecture in which the 1 mu m and the 1.5 mu m signals are generated in independent cavities that share the identical active fiber. The mode-locking of the 1 mu m laser is realized via nonlinear polarization evolution (NPE), whilst the 1.5 mu m laser is mode-locked through cross-phase modulation (XPM) induced by the 1 mu m laser and the mode-locking is further stabilized by NPE. Synchronized dual-band mode-locking operation is achieved using the laser.
