We experimentally report the novel evolutions of dissipative-soliton-resonance (DSR) pulses with respect to the pump power in an all-normal-dispersion fiber laser based on a nonlinear optical loop mirror. By solely increasing the pump power, pulse br

The laser frequency of an Er-doped fiber ring cavity is stabilized using the microbubble resonator (MBR) as the feedback element. The linewidth of the laser is nearly 86 MHz at ~1560 nm measured by the Fabry-Perot interferometer. Since the thermoopti
