  The ignition at the National Ignition Facility (NIF) set off a global wave of
research on the inertial fusion energy (IFE). However, IFE requires a necessary
target gain G of 30-100, while it is hard to achieve the fusions at such high
gain with the energy, configuration, and technical route of the NIF. We will
present a conceptual design for the next generation laser driver of 10 MJ, 2~3
PW at the laser wavelength of 0.353 micrometer (or 0.353 micrometer, then the
energy and power can be higher), and 1 shot per 30 minutes, which is efficient,
compact, low-cost, low laser-plasma instabilities, applicable to multiple laser
fusion schemes, and aiming for G > 30.
