How to Drive Diode Laser Costs to One Cent per Watt

Any viable laser fusion power plant will depend on dramatically cheaper laser diodes. Developing them is a major challenge that requires higher production output and technological advancements. High-power diode lasers have become the workhorses behind laser materials processing. They pump the kilowatt-class fiber lasers for cutting and welding, making them the backbone of this ever-expanding multibillion-dollar market. …
