Direct vs Indirect drive for fusion

    What is so good about having a hohlraum, and is it destroyed after every pulse?

    It serves to provide a relatively uniform source of radiation at shorter wave lengths as it absorbs the laser pulse and heats up.
    It is of course destroyed in the process.
    The painful reality is that laser fusion has shown itself to be an equally thorny path to controlled fusion as magnetic confinement is. Either approach is still at least an order of magnitude or two short of what is needed, despite huge investments.
