Laser intensity scalability analysis for p-B11 fusion via microbubble implosion

Microbubble Implosion (MBI) is an emerging concept in laser-matter interaction that utilizes ultra-high intensity laser (UHIL) pulses to trigger the collapse of micrometric spherical cavities, achieving extreme matter densities. This mechanism offers a promising new pathway to reach nuclear fusion reactions and target the production of alpha particles. A critical factor in MBI efficiency is the interplay between cavity geometry and laser intensity. This study investigates this correlation through numerical simulations using a Particle-In-Cell (PIC) code. The findings characterize the fundamental scaling laws and basic properties of the implosion, providing a framework essential for the design of upcoming experimental campaigns.
