Terahertz time-domain spectroscopy (TDS) is nowadays well-established to study a variety of low-frequency motions in condensed matter. However, whereas immense progress has been made in the development of single-cycle THz sources for TDS, many studies continue to suffer from the low average power, that result in extremely poor signal-to-noise ratio and impractically long times. Increasing the average power of current THz-TDS sources calls for more powerful, state-of-the-art NIR ultrafast driving lasers. In this talk, we will present latest progress in high-power ultrafast disk oscillators, as well as their application for the generation of high average power THz radiation. We will report on record-high THz powers in the few to tens of milliwatts regime, and will present future applications enabled by these unique sources.
