A single-cavity all-fibre laser operating at GHz rates is demonstrated as a promising approach for fast spectroscopy. Multimode-interference-based spectral filtering in the laser enables dual-wavelength mode-locked pulse generation (thus, dual-comb emission) with a 148 kHz repetition rate difference. The GHz dual-comb laser exhibits excellent stability and can be used for outdoor measurements.
