- This study has shown that laser supported combustion waves (lscw's) are generated and that they can reach critical density. More critical density plasmas are formed as the angle of incidence approaches the normal. As the angle of incidence is increased the penetration increases. The vapor plume is seen to precess about the surface normal which indicates motion of the molten pool. The penetration increases correlate with fewer critical density plasmas implying that better photon conversion is obtained when the plasma is absorbing and not at the critical density. The radiation monitoring techniques provide data which correlates with penetration and thus are potential monitoring and control methods.
