Résumé
Dual frequency-combs have been relevant for applications such as spectroscopy [1], Many methods are used to generate dual-combs like polarization multiplexing [2] or wavelength/space multiplexing [3,4]. We demonstrated two passively mode-locked dual-comb configurations in a single Vertical External-Cavity SurfaceEmitting Laser (VECSEL) using a InGaAs/GaAs based optically-pumped gain mirror (1/2-VCSEL) and a fast Semiconductor Saturable Absorber Mirror (SESAM) for an emission at 1.06µm with a pulse width of 5ps at 1GHz repetition rate.
