| Abstract: | The study of coupled electromagnetic and thermo-mechanical processes concerning with a focused high power laser explosion in gas medium is now becoming an important research forefront.The subject includes a series of energy absorption and transfer processes,such as ionization and optical breakdown in mixture gases, the evolution and propagation of the laser supported combustion wave(LSC) and laser supported detonation wave(LSD) in gas-plasma. In fact,these very complex processes can be macroscopically consi... |
