Polarization-Maintaining, Harmonically Modelocked Soliton Fiber Laser With Repetition Rate Stabilization Using Optical Pumping Of A Saturable Bragg Reflector

Well-organized harmonic modelocking with up to 12 pulses in a 1.5 um polarization-maintaining erbium soliton fiber laser is achieved. With eight pulses in the cavity, repetition rate timing jitter is suppressed by 7.3 dB through optical pumping above the absorber bandgap. This stabilized laser operates at 463 MHz with nearly transform-limited, 660 fsec, 1.0 pJ pulse.
