Femtosecond laser pulses are indispensable for high-precision measurements with high-temporal resolution and sensitivity in quantum technologies and spectroscopy, but also in the efficient characterization of materials. However, as the complexity of the experimental set-up increases, so too does the demand for reliability and ease of operation of the laser itself. If ultrashort-pulse lasers are to serve as the basal elements of highly complex systems, they must meet demanding specifications with respect to stability, spectral reproducibility, and insensitivity to external conditions. The collaborative efforts of Neaspec and Menlo Systems are bringing commercial systems onto the market, which combine near-field microscopy and spectroscopy with coherent radiation in the terahertz region. Initial applications are envisaged in the non-invasive and contact-free characterization of semiconductor architectures and other materials whose operation is a function of the concentration and mobility of the charge carriers they contain. This relatively new method for probing the properties of novel functional materials could both simplify and stimulate the further development of these compounds.
