Progress in inertial fusion at LLNL
Abstract
Experiments at LLNL using the 10 TW Novette laser led to significantly increased understanding of laser/plasma coupling. Tests using 1.06 micrometers, 0.53 micrometers and 0.26 micrometers light show increased light absorption, increased efficiency of conversion to X-rays, and decreased production of suprathermal electrons as the wavelength of the incident light decreases. The data indicate that stimulated Raman scattering is the source of the excessive hot electrons and that the effect can be controlled by the proper selection of laser frequency and target material. The control of these effects leap to achievement of higher inertial fusion target compressions and to production of the first laboratory X-ray laser.
