Abstract
White-light-seeded noncollinear optical parametric amplifiers (NOPAs) are very powerful tools for the generation of few-optical-cycle laser pulses broadly tunable in the visible [1, 2], So far, however, the pulse energy of NOP As has been limited to the 10-μJ range, limiting their use to time-resolved optical spectroscopy. Here we report on the energy scaling of a NOPA up to «500 μj, more than an order of magnitude higher than previously published. This scaling makes the NOPA a very promising source for high-intensity, extreme non-linear optics applications. As an example, we demonstrate the generation of high-energy tunable ultraviolet (UV) and of vacuum ultraviolet (VUV) pulses.
