We demonstrate a fiber ring laser based on a single-walled carbon nanotube (SWCNT) wall paper absorber. It is found that the proposed Yb-doped fiber laser can either be operated in the mode-locked states or Q-switched states. First, SWCNT wall paper acts as a mode locker when the pump power is below 80 mW. Self-started mode locking can be obtained when the pump power is about 47 mW. The proposed Yb-doped...
We compare the timing noise properties of three most typical carbon materials, i.e., single walled carbon nanotubes, graphene and graphene oxide as saturable absorbers in a passively mode-locked Er-doped fiber laser as a test platform.
Experimental observations of multiple dissipative solitons are reported in a fiber laser with large normal-cavity-dispersion. Eight solitons can be generated from the laser cavity at pump power of about 310mW. Results show that the stable propagation of dissipative solitons may be limited by the accumulation of excessive pulse chirps.
