Ultra-high harmonics of short-pulse lasers constitute a promising novel source of brightness, coherent XUV radiation. To date, though we have demonstrated that short wavelength, KrF (248-nm) lasers produce harmonics both efficiently, and with high photon energy, the two experiments we have performed have used far from ideal focal spots. Recent improvements on the Titania Laser, along with the close to diffraction limited operation of KrF-pumped Raman systems, affords the opportunity to spectacularly increase the spectral brightness of these sources, close to brightness of XUV lasers at the long-wavelength end of the scale, and further extend the photon energy toward the water window. Exploitation of a novel beat-wave harmonic scheme will illucidate the underlying physics of two-colour operation. Simulations indicate that this method of harmonic production retains the high efficiency of short-wavelength primary drivers, combined with the low energy interval between harmonics normally found with long-wavelength drivers.Finally, we propose to exploit this high brightness source to investigate the opacity of shocked materials, with greater spectral coverage than can be obtained with a monochromatic XUV laser.
