Revisiting Fire Safety Guidelines in CO₂ Laser Airway Surgery. [PDF]

Laryngoscope
This experimental study evaluates fire risk during CO2 laser airway surgery using high‐flow and jet ventilation in a porcine model. Results showed that laser wattage had a greater influence on fire risk than FiO2, with jet ventilation consistently producing expansive flames.

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.

Investigation on the origin of hot electrons in laser plasma interaction at shock ignition intensities

Scientific Reports, 2023
Shock Ignition is a two-step scheme to reach Inertial Confinement Fusion, where the precompressed fuel capsule is ignited by a strong shock driven by a laser pulse at an intensity in the order of $$10^{16}$$ 10 16 W/cm $$^2$$ 2 .
