    Regenerative Pulse Sha**: A New Technique for Ultrabroadband Amplification

    Regenerative pulse sha** is used to amplify sub-20 fs pulses, and to produce ~100-fs pulses centered at different wavelengths for difference frequency mixing in the 6–12 µm range.

    Ultrafast Ionization Dynamics in Laser-Driven Clusters

    We have modeled the ionization dynamics of rare gas clusters induced by ultrashort laser pulses (15fs). High ionization levels are reached within femtoseconds, producing pulses of energetic electrons. Inner sh...

    Chirped-Pulse Amplifiaction with a Fiber Stretcher and a Grism Compressor

    We demonstrate chirped-pulse amplification of femtosecond pulses using a fiber stretcher. We use a grism pair to achieve the highest single-stage compression factor (750) ever obtained from a fiber.

    Time-resolved x-ray diffraction study of ultrafast acoustic phonon dynamics in Ge/Si-heterostructures

    Using time-resolved x-ray diffraction the ultafast strain dynamics in fslaserexcited Ge/Si-heterostructures has been studied. A fluence dependent, anharmonic dam** of the impulsively generated acoustic phono...

    Direct Observation of Ultrafast Non-thermal Melting by Ultrafast X-ray Diffraction

    Ultrafast nonthermal melting of femtosecond laser-irradiated germanium was observed directly for the first time using sub-picosecond. 1.54-angstrom x-ray diffraction. Such measurements allow the study of trans...
