Abstract

We review the present status of our research on the generation of coherent soft x-ray radiation using high- intensity picosecond Nd:glass laser pulses. We adopt two completely different methods for this purpose, that is high- harmonic generation from solid-vacuum interfaces, and longitudinally pumped transient collisional excitation Ni- like Mo x-ray laser. Unexpected jetlike structures are observed in the visible emission of the longitudinally- pumped molybdenum plasma, extending over a length of several millimeters. Efficiency of harmonic generation from near- solid density plasma is found to increase by a factor of 2 to 3 when using prepulses.
