Abstract
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.
