Dissipative soliton erbium-doped fiber laser based on hybrid mode-locking
The dissipative solitons with high stability and wide spectrum are obtained from a simple and all fiber hybrid passively mode-locked erbium-doped fiber laser. The laser combines two mode-locked mechanisms of saturable absorber and nonlinear polarization rotation, and operates in the normal dispersion region. Through dispersion management, the laser can generate a series of soliton pulses with spectral width of 39.1 nm and pulse duration of 178 fs. The wavelength of laser operation is 1.55 μm, the repetition frequency is about 34.3 MHz, and single pulse energy is evaluated to be 0.33 nJ. At the same time, the laser also possesses the slope efficiency of about 15.5%; at room temperature, the laser can realize self-starting mode locking, and the operation time in the stable state of a single pulse output is more than 15 h.
