Heat wave fast ignition in inertial confinement energy
High Power Laser Science and Engineering, 2013 An accelerated micro-foil is used to ignite a pre-compressed cylindrical shell containing deuterium–tritium fuel. The well-known shock wave ignition criterion and a novel criterion based on heat wave ignition are developed in this work.

Chaotic behavior of quantum cascade lasers at ignition
Communications in Nonlinear Science and Numerical Simulation, 2021 The ignition of Quantum Cascade Lasers can occur from a state of oscillating fie ld domains. Here, the interplay between lasing and the kinetics of traveling dom ain boundaries provides complex oscillation scenarios. We analyze our numerical findings in detail for a device operating at terahertz frequencies and manifest chaotic evolution by positive ...
