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.
