High average and high-peak power femtosecond sources are ideal primary sources for nonlinear generation of extreme ultraviolet (XUV) and mid-infrared (MIR) radiation. Our progress in the development of such sources lasing at 1 µm and 2 µm central wavelengths is presented. This includes thin-disk oscillators delivering record values of more than 250 W average power, pulse durations 8-250 fs at repetition rates of 10-250 MHz. MIR optical parametric amplifiers driven by these oscillators and delivering average power of few watts in the range 4 µm and 8 µm are demonstrated. New developments in the field of 2 µm Ho: YAG and Cr: ZnS oscillators are also presented. The 2 µm femtosecond oscillators are especially interesting for nonlinear conversion into the MIR range. Prospective and first trials in the use of these sources in time-domain mid-infrared spectroscopy are discussed.
