Date Aug. 29, 1996A laser arrangement for recovering a clock from a modulated optical input signal (So) has, between a resonator mirror (21) for launching the input signal and a resonator mirror (42) for coupling out the recovered clock (T), a bidirectional optical transmission channel (3) having at least two nonlinear optical amplifiers (2, 4) and a demultiplexer (6) between the amplifiers. The arrangement is operated as a mode-locked laser and is suitable for optical repeaters.
