The manuscript presents a conceptual fusion scheme based on laser-driven plasma physics, exploring an alternative pathway for initiating p–¹¹B fusion reactions. The proposed approach employs a spherically symmetric micro-scale fuel target combined with a multi-channel, temporally delayed laser irradiation architecture. Rather than relying on extreme compression or long-lived magnetic confinement, the study focuses on extending the effective reaction window through geometric design and pulse-timing strategies. The main contribution of this work is a qualitative and physics-based discussion of how key challenges of p–¹¹B fusion—such as short confinement time, limited burn fraction, and alpha-particle escape—may be mitigated by controlled laser–plasma interaction geometry and synchronized energy deposition. Numerical optimization and reactor-scale performance metrics are intentionally kept to a minimum, with emphasis placed on physical mechanisms, system architecture, and conceptual feasibility. We believe that this manuscript aligns well with the scope of Nuclear Fusion, particularly its interest in advanced fusion concepts, alternative fuel cycles, and innovative plasma initiation methods. The work is intended to stimulate discussion and further investigation rather than to present an immediately optimized reactor design.
