“…ation of suprathermal x rays is a very different phenomena from thermal emission (Priedhorsky et al, 1981;Burnett et al, 1984;Hauer et al, 1984;Forslund and Goldstone, 1985). In essence, the process amounts to the use of the absorbed laser energy to produce an electron beam, which in turn has many similarities to a classical xray tube.…”

“…Hot electrons that are confined to the coronal region by the sheath and self-generated magnetic fields (Forslund and Brackbill, 1982;Forslund and Goldstone, 1985) can impart a significant portion of their energy to ions. In CO 2 laser experiments at high intensity (~ 10 16 W/cm 2 ), as much as 60% of the absorbed laser energy has been measured in protons with > 100 keV energy (Hauer et al, 1984). A very simple model of the ion acceleration gives some feeling for the mechanisms involved.…”

“…Shorter wavelengths (A < 1 /zm) are more efficient for producing quasi-thermal plasma emission (Yaakobi et al, 1981). Longer-wavelength (A > 10 /zm) laser interactions have the additional feature of producing large numbers of suprathermal elections that in turn produce hard x-ray line radiation and bremsstrahlung (Hauer et al, 1984). Equally remarkable is the particle emission from LPs.…”

This report describes several new applications of laser-produced plasmas that have arisen in the last few years. Most of the applications have been an outgrowth of the active research in laser/matter interaction inspired by the pursuit of laser fusion. Unusual characteristics of high-intensity laser/matter interaction, such as intense x-ray and particle emission, were noticed early in the field and are now being employed in a significant variety of applications outside the fusion field. Applications range from biology to materials science to pulsed-power control and particle accelerators.
