Paper Abstract

Efficient harmonic generation was achieved using a long argon gas jet pumped by intense 28 fs laser pulses. By balancing diffraction and plasma defocusing with nonlinear self-focusing, we could achieve a new optimum condition for efficient high-order harmonic generation. Under condition of a self-guided laser pulse, generated high-order harmonic signal was strong enough to saturate an x-ray CCD in one laser shot of a few mJ.
