Abstract
We present experimental and theoretical results on ultrashort soft-x-ray harmonic generation in gases, using art amplified Ti:sapphire excitation laser with a 25-fs pulsewidth.1 The bandwidth of the excitation pulses is 32 ran, centered at a wavelength of 805 nm, and the laser system can provide up to 70 mJ of energy per pulse at a 10 Hz repetition rate. The laser beam is focused by a curved mirror onto a gas terget to generate the high harmonics, and the spectra are taken with use of a grazing-incidence soft-x-ray spectrometer.
