Abstract :
Pulses at soft X-ray wavelengths with a duration of less than 1.5 ps were produced by focusing high-intensity, ultrafast visible laser pulses onto a solid. Reflectivity measurements indicate that the laser pulses are absorbed by a plasma formed just inside the surface of the solid before expansion occurs. The observed emission spectrum is characteristic of a high-temperature, short-lived, high-density plasma. Applications of the ultrafast X-ray pulses, including an X-ray laser scheme, are discussed
