high-power single-cycle source of coherent optical pulses exists in the important region of the spectrum between 5 and 30 microns. Ti:sapphire1ped OPA/OPGs are typically limited to 10-cycle pulses, at wavelengths up to around 10 microns, with maximum energies of around 1 rojoule. W e propose to use the FELIX free-electron laser to produce single-cycle pulses over this entire wavelength range with energies in sss of 100 microjoules. These high-intensity pulses will find immediate application in experiments involving resonant vibrational ladder climbing hall molecules, and in coherent measurements of femtosecond relaxation dynamics in solids and liquids, e.g. semiconductors and doped lating bulk crystals.IX is especially suited to this task since it has recently been shown to operate in the superradiant regime - with a route to ultrashort optical )s linked to an achievable reduction in laser cavity losses and an increase in electron bunch charge. An electron/photon pulse-length iostic, a pivotal component in the improvement of the laser performance, will be developed further as an integral part of this programme of This device has applications beyond free-electron laser physics, especially in high-energy particle accelerators.high peak power levels will be generated by chirped-pulse parametric amplification of the FELIX output power in an AgGaS2 crystal, and high ral intensities within 30ps pulses will be produced via narrow-band amplification of the FEL pulses using similar techniques.
