Abstract
This paper describes the generation of tunable synchronized dual-wavelength picosecond pulses, based on a novel configuration for a actively mode-locked laser-diode array, consisting of an intracavity folded dispersive delay line having a V-shaped double-stripe mirror. Optimization of the intracavity dispersion yielded 29 ps pulse width for each wavelength. Translation of the V-shaped mirror vertically, resulted in tunability of the spectral separation between the two wavelengths from 2 to 11 nm.
