Abstract :
In this paper, we compare the results of experiments on spectral transformation of ~5-fs, 0.1-0.3-mJ input IR laser pulses into the DUV in a high-pressure gas target with simulations performed by numerically solving a field-evolution equation for a few-cycle pulse undergoing spectral, temporal, and spatial nonlinear-optical transformations in an ionizing gas medium. Gas-phase harmonic-generation techniques can produce few-cycle pulses with a pulse width less than 1 fs in the UV/DUV range.
