Extreme CPA Laser Pulses for Environmentally Clean Laser Boron Fusion

Abstract The importance of the development of chirped pulse amplification (CPA) was highlighted with the award of the 2018 Nobel Prize in Physics to Gerard Mourou and Donna Strickland. CPA laser physics opens the way to exciting new advances in laser applications including laser fusion. As noted in this paper, its application to laser fusion enables ultrahigh power levels for ignition of laser fusion systems without requiring thermal pressures and millions of degrees centigrade. Instead, nonthermal pressures are driven by nonlinear force to create ultrahigh picosecond acceleration of plasma blocks. This paper discusses the exciting possibility of using CPA with block ignition to provide a new route for burning the environmentally clean fusion of hydrogen–boron-11 (HB-11) fuel.
