Abstract:

It has been found experimentally that emission spectrum of the plasma initiated by a water droplet upon exposure to a pulsed CO2 laser radiation of microsecond duration exhibits X-ray spectral components. Possible physical mechanisms of this emission and its characteristic spectra are discussed.
