Abstract. We are carrying out a coordinated, focussed effort to develop
Laser Inertial Fusion Energy. The key components are developed in concert
with one another and the science and engineering issues are addressed
concurrently. Significant progress has been made in this program: We are
evaluating target designs that show it could be possible to achieve the high
gains (>100) needed for a practical fusion system. These have a
low density CH foam that is wicked with solid DT, and overcoated with a thin
high-Z layer. Significant advances have been made with the two types of
laser are being developed: Krypton Fluoride (KrF) gas lasers and Diode
Pumped Solid State Lasers (DPPSL). Both have the potential to meet the
fusion energy requirements for rep-rate, efficiency, durability and
cost. This talk will also present the advances in target fabrication
(advanced foams and high Z overcoats), target injection (new facility for
target injection and tracking studies), final optics (aluminum at grazing
incidence has high reflectivity and exceeds required laser damage
threshold), and development of chamber operating windows (target survival
plus no wall erosion). * Sponsored by the US DOE, NNSA/DP
