Synchronized two-color operation of a passively mode-locked erbium-doped fiber laser by dual-injection locking

Summary form only given. The simultaneous operation of a passively mode-locked laser at two different wavelengths is important as a source for high-pulse-rate, wavelength-division multiplexing (WDM) schemes, for wideband pump probe and four-wave mixing experiments. Using the recently introduced harmonic injection-locking scheme, we achieved synchronized locking of a passively mode-locked fiber laser, at two wavelengths (1.53 /spl mu/m and 1.55 /spl mu/m) simultaneously, producing pulses of several picoseconds with 7.5-GHz pulse repetition rates. Because the same scheme can also serve as a storage ring, this work demonstrates the feasibility of a two-color memory ring.
