High-precision passive stabilization of a dissipative soliton resonance laser repetition rate based on optical pulse...

I present what is believed to be the first demonstration of using the cross-phase modulation (XPM) effect to achieve high-precision, all-optical synchronization and stabilization of the pulse repetition rate of a dissipative soliton resonance (DSR) mode-locked (ML) fiber laser working in the 1.06 µm wavelength range. Nanosecond 1.55 µm Master oscillator pulses were injected into the Slave cavity of the DSR laser to induce the XPM effect and subsequently synchronize both repetition rates. When referencing the Master laser to a rubidium frequency standard, the fractional instability of the DSR ML laser pulse repetition rate reached 1.26 × 10^-12 for 1000 s integration time. The locking range and stability of the XPM synchronization are experimentally verified under varying conditions and discussed in the paper.
