Asynchronous optical sampling terahertz time-domain spectroscopy using semiconductor laser-based ultra-short pulse sources is demonstrated. A pair of hybridly mode-locked edge-emitting external cavity lasers operating at a wavelength of 830 nm is used. Terahertz traces with spectral components over a range of 250 GHz are achieved.
