We report here exploratory studies of direct-drive target designs that require substantially less than a mega joule of laser energy for ignition and moderate gains. The target physics advantages of the Krypton Fluoride laser are exploited to achieve increased implosion velocities that allow ignition and gain at reduced energy. Use of increased laser irradiance allows use of limited aspect ratio targets. The highest performing designs make use of a short spike prepulse to set up an adiabat that can be favourable to gain. These designs have application in reducing the driver size needed for experimental laser fusion facilities and may be applicable to the gains needed for the energy application.
