Direct laser fusion system

A laser fusion system, the system comprising:

• a reactor housing, the reactor housing having a diameter and defining an interior region maintained in a vacuum environment;
• wherein the interior region comprises a reaction region at a center of the reactor housing and a peripheral region surrounding the reaction region;
• a fuel target disposed in the reaction region at the center of the reactor housing;
• a plurality of mirrors positioned on an interior surface of the reactor housing, the plurality of mirrors arranged in N pairs, where N is greater than or equal to 10, each pair of mirrors comprising a first mirror and a second mirror diametrically opposed to the first mirror, wherein each pair of mirrors defines a Fabry Perot resonant cavity that extends linearly from the first mirror to the second mirror along the diameter of the reactor housing and intersects with the center of the reactor housing;
• N laser light sources, each source coupled to the first mirror of each pair of mirrors and configured to emit a laser beam to the first mirror such that the laser beam propagates in the respective Fabry Perot resonant cavity between each respective pair of mirrors and increases in intensity from a first intensity to a second intensity for M cycles, where M is greater than or equal to 1000;
• and
• wherein each laser beam in each Fabry Perot resonant cavity intersects within the fuel target to cause nuclear fusion.
