Polarisation-maintaining, harmonically modelocked soliton fibre laser with repetition rate stabilisation using optical pumping of saturable Bragg reflector

Well-organised harmonic modelocking with up to 12 pulses in a 1.5 µm polarisation-maintaining erbium soliton fibre 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 stabilised laser operates at 463 MHz with nearly transform-limited, 660 fs, 1 pJ pulses.
